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.

    Avoiding Duplication

    I need some help figuring out how to avoid duplication of event guests for multiple locations in one table.

    I have an event table that I use for organizing banquet guests (banquetb). To avoid entering the same person for an event more than once I have set up in the field rules in the validation tab the uniqueness test "Value of field must be unique" for the ID_Number of the person. It has worked great for many, many years to help me avoid guest duplication.

    My problem is that I am now moving three banquet events at three separate locations into one month using the one table (banquetb).

    I have an ID_Number and a Location field to separate the person for the specific location. I now have a situation where the same guest may go to all three events, but I have not been able to set up a uniqueness test that will allow the ID_number to be repeated, but not in the same location more than once. I have tried several options, but have not gotten it to work.

    In other words I want to block the same person from being entered twice for one location, but allow the person to be allowed more than once with potentially three locations in the same table. I am hoping this makes sense and that a seasoned A5 user will have a suggestion to make this happen.

    I have attached a view of a form I use in the Banquet.set to enter the guests for the events. Given the view I would like to avoid having ID_Number -04910 duplicated in the Brunswick location, but the ability to duplicate ID_Number -04910 in another location for example Camden.

    I have tried some expressions in the field rules like mentioned above, but it has not blocked the duplication.

    Any suggestions to remedy my ability to prevent guest duplication at one event while allowing duplication to more than one event would be greatly appreciated.

    Re: Avoiding Duplication

    Instead of "Value of field must be unique" I think you now must move to ""Value of expression must be unique" with the expression combining the id and the location.

    Uniqueness Test for Multiple Fields in a Record
    There can be only one.

      Stan,

      That is exactly what I thought and tried, but it did not work. I made the expression (Id_Number+Location). I thought it would solve the issue, but it allowed me to save the record with the same values. I even created a field that combined the two and it did not stop the duplication. I will try this again, just to make sure, but I did at least try and go this route. Thanks for the quick input.

        Stan,

        Okay I am eating humble pie. For whatever reason I did not see your link until tonight.

        When I did my expression I did not do it in both fields and the link gave me the information to make that change. Works like a charm.

        Once again, I am grateful for your quick input and please forgive me for my oversight of the link that solved the issue. You have me back in shape and ready to have three successful events in October. Thanks.
