Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

    Re: Subelement Not Found

    the date value could have been
    update.expr4 = "null_value(),DATEREV)"
    But I had a filter attached

    Stans images show the same way I did it in operations

      Re: Subelement Not Found

      Hello Stan,

      Your assumption is incorrect. The button is on a Menu form based on a dummy Table. The app is set t open to the Menu form. Thus there should not be anything open which contains data. When the button is pressed, it throws the error. Right now, I am on my laptop and using a backup of the app. The app opens, I click the button and this error pops up:

      Script:Datapurge1 line:11
      t.change_Begin()
      Change already began

      Well, isn't that interesting, especially since the first line of code in the script is parentform.commit(). Also, line 11 is a commented out line of code referring to a numerical field. That begs the question, What, exactly, does the error message mean and to what is it referring? Does it mean the error is on line 11? Does Alpha count commented out lines as well as empty or blank lines when it throws an error code? After some experimenting, I know that Alpha counts empty lines and commented out lines.

      I edited my script so only character fields were evaluated. I closed the app and reopened it. Clicked the button and nothing happened except in the lower left corner of the screen appeared the words, Record 1. I clicked on the Control Panel tab and Alpha locked up. After several attempts of this procedure, each time Alpha locking up, I commented out the 4 lines of code referring to the loop, saved the script, closed and reopened the app. Clicking the button resulted in no error codes and in the lower left corner, the words Record 1 made a very brief appearance. I clicked the CP tab and no lockup. The CP opened.

      OK, I opened the script and uncommented the 4 lines of loop code. After saving an exiting the app and reopening it, I clicked the button and the same thing happened, Record 1 appeared and did not disappear. (That's probably when Alpha locked up) I clicked the CP tab and had to close the program as it was frozen solid.

      OK, so what's with the looping code? Why is it not throwing an error message? I have no clue but I'll keep working with it.
      TYVM :) kenn

        I figured out that the Change already began error message occurs no matter what was opened. Experimenting, I copied Stan's code and pasted it into my script, replacing all except the commit line. When I clicked the button, it threw an error because there is a line of code referring to a field that is not in this version of the app. I removed the line from the script and saved it. Clicked the button and the Change already began error appeared. The ONLY form and table that had been opened was the Menu form/Dummy table. The script editor was closed as well.

        I ended up commenting out the 2 fields in the script which are not in this version of the app as well as one of 3 date fields along with the 4 lines of looping code. As long as those 4 lines are not in the script, it runs, even with the numerical and other 2 date fields intact. It ignores the numeric and date fields but it runs, nulling the character fields as directed.

        SUMMARY

        Alpha does not like the lines of looping code and will lock up if included. Why, I have no clue. However, I will try created an update operation without the genie and see what happens.

          Re: Subelement Not Found

          I was able to create the update as Stan suggested. I works beautifully from the operation tab. However, action scripting to run the operation from a button does not work. I chose Operation, Run a saved operation. Next, I chose the Summarytest table and that's where the problem lies. It will not allow any table to be accepted because the window stays open showing all the available tables. The script can be completed but the table selection window stays open and the default prompt appears to create an operation.

          OK, enough, it's 2:21 and time for some zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz
