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.

    Update using another field value

    I want to update an estimated price field. The update espression is
    When designing the update, the values evaluate correctly. However, when I run the update, the resulting values are 0.
    If I change the "User_Date->Price_Multiplier" to a value, it works fine.
    Why won't it work when I use the "User_Data->Price Multiplier" field?

    RE: Update using another field value

    Richard, please clarify. Are you talking about running a saved update operation, or something else?

    If it's a saved update operation, do you have any forms open when it's run that are based in part on the same tables involved in the update? i.e. are you running it from a button on a form?



      RE: Update using another field value

      Yes, it is run from a button on a form. The form is based on the table "Products",which is the same table referenced in the set used to run the update.

        RE: Update using another field value


        It's very likely that the problem is occurring because saved update operation assumes it has to open the table for you. Since the table is open already (it opened whenthe form was opened), when the update operation opens it, Alpha Five assigns an alias name to that instance of the table, that's different from the actual table name. The update operation expects to be working with Products, and it's really working (or trying to) with Products1. The naming conflict causes theproblem, at least that's my guess.

        Stan Matthews explained the fix for this thing as well as anyone. Search this forum for his posts on 'operation'. You'll find a good discussion explaining the solution for you. Basically, you have to modify the script which the saved update operation is using, so that instead of opening another instance of the table, it uses the 'current' instancce.

          I could not find the post you referred to.
          I tried closing all forms and then running the update. It still does not work. If the problem is casued by multiple instances of a table being open, shouldn't the update run OK when all forms are closed?

            Yep, you're right, something is definitely out of kilter here. Any chance you could email me a copy of the database, with a short message explaining which tables, forms, and saved operation you are wrestling with. We should be able to nail this down quickly. (...famous last words!)
