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.

    Range and date operations

    Hi, I'm not able to code, this is a limit for me but I'm trying to learn without having enough time....

    So I need help with a little complicated operation.

    I have a table with one row for every day and a total field.
    Now I would like to make a report that compares results for a range that is from the first day of the year to today, for every past year.

    Something like:
    01/11/2007 - 11/02/2007 = 1000
    01/11/2006 - 11/02/2006 = 1200
    01/11/2005 - 11/02/2005 = 999
    01/11/2004 - 11/02/2004 = 1002
    .....Etc.

    I tried a lot of things and I am close to make it, but something goes wrong.
    I found functions that adds years or months but not detract it...

    I'm pleased if somebody wants to help me....thank you.

    Code:
    ? addyears(date(),-1)
    = {11/02/2006}
    
    ? addmonths(date(),-1)
    = {10/02/2007}
    There can be only one.

        Glad to help. Sometimes you can do that and in other cases it might not work.

        Code:
        ?left("Luca",-1)
        = "Luc"
        
        ? right("Luca",-1)
        ERROR: Value of argument is out-of-range
        Always worth a try.
        There can be only one.

          Another thing Stan,
          how is the expression for the total between a range of dates stored in variables?

          Now I am using a total grand and then modifying the filter of the table,form, report. But is quite a limiting way...

            I'm not sure I understand but I think you are asking for

            tablesum("tablename","between(some_date_field,{"+dtoc(addyears(some_date_variable,-1))+"},{"+dtoc(some_date_variable)+"})","some_field_to_be_totaled")
            There can be only one.
