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.

    look up field

    version 10.5 build 3387-3602
    desktop

    Hello

    I have three tables(the following is an example)
    table#1 country
    id: numeric auto_increment length 3
    name: char length 25
    data
    0,usa
    1,chile
    2,spain.
    table#2 region
    id: numeric auto_increment length 3
    name: char length 25
    country: numeric length 3
    data(as shown on the default form, the values stored are 0,1)
    0,california,usa
    1,maipo,chile
    table#3 item
    id: numeric auto_increment length 3
    name: char length 25
    country: numeric length 3, lookup tied to country.dbf with name only showing on the drop down window.
    region: numeric length 3, lookup tied to region.dbf with name only on the drop down window, filter expression:country=item->country.
    data(as shown in the default form)
    0,a,usa,california
    1,b,chile,maipo
    2,c,spain
    (on record #3 I,purposefully, did not enter the region)
    all is fine so far.
    however if i go back and remove california to keep blank I get the message "empty expression" or go back and change usa to chile or spain then there is no problem?
    Question: Is this normal or how do I change the design?
    Thank you all.

    I think this may be the problem. You need to put both the CountyId (Display No) and CountyName (Display Yes) into the field rule lookup. This way you're showing the Country Name and then using the Country ID.

      Thanks for your reply.
      That is how I did the lookup window, The name field, however, is not used to fill anything in the item.dbf. And I can not even try since there will be type mismatch. The id field is numeric and the name field is char.

        I still think this is on the right track for you. Attached is a database that has what you want... I think. Have a look at the tables. Ignore the ASCII stuff - that's for something else.
