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.

  • calculated field expression

    hi all,

    how I can put some thing like this in calculated field expression:

    if(M_filter = "Oil", M_filter_oil_price, 0)
    if(M_filter = "Air", M_filter_air_price, 0)
    if(M_filter = "Fuel", M_filter_fuel_price, 0)

    Please any help or suggestion !?
    Best Regards,

    result = case(M_filter = "Oil", M_filter_oil_price,M_filter = "Air", M_filter_air_price,M_filter ="Fuel", M_filter_fuel_price..

    Apologies if this has already been answered, I called away for a couple of hours

        I tried this assuming that M_filter_oil_price, M_filter_air_price, and M_filter_fuel_price are seperate fields for each record.
        I created a calculated field named Cprice in the Query(DBF) section, with the following code
        Code:
         case(M_Filter="Oil",M_Filter_Oil_Price,M_Filter="Air",M_Filter_Air_Price,M_Filter="Fuel",M_Filter_Fuel_Price)
        This accomplishes what you asked for, but does not seem to be what you really wanted.

          Case is a valid function. But I guess it depends where you are defining it. If you are partial to IF, try this:

          if(M_filter = "Oil", M_filter_oil_price, if(M_filter = "Air", M_filter_air_price, if(M_filter = "Fuel", M_filter_fuel_price, 0)))

            Re: calculated field expression

            I tried using IF in the clientside calculations, but kept getting a circular reference error.

              Where are you using this?

                Hi Peter,

                The attached pic says it so much better than I can.

                I know I didin't get to the false part of the statement, but the error showed up before I got that far.

                  Yeah, client side expressions are basically JavaScript. Alpha gives us some basic "wrapper" functions, but they are very limited.

                      Where are you planning to put that code (I'm a bit curious because of the trouble I had with it) ?

                        What's "a result_false" in the else part of the statement? It looks like that is what's causing the problem - it would be interpreted as 2 variables or field names. Peter's "if" statement works in the client-side properties, calculated field expression - you're allowed the nested if statements in there - it gets converted to the equivalent javascript nested if statement.

                          I tried it exactly as described, and I still get the error (please see attached image).

                            Re: calculated field expression

                            Now we need to find out what M_filter, M_filter_oil_price, M_filter_air_price, and M_filter_fuel_price are, Are these calculations that reference themselves? A circular reference is a variable, field, etc. that references itself in the calculation thereby creating a reference that goes around and around in a circle and can never be evaluated.

                              They are fields.
