I would like to validate a two field combination to ensure that no duplicates are allowed. For example, one field is a color and the second field is an object (i.e. Red balloons, Orange Hats). This is straight forward for one field however, I cannot find a way to accomplish this with multiple fields. If I try to create a combo text field using the calculaiton method only the first field is displayed. I cannot find a way to validate a calculation field as an alternative.

Thanks much

It's possible but it's complex. What you're trying to do is something called cross-field validation, and there is a technique for it which is outlined in Scriptology (great book, if you don't already have it). If you get the book, there's a sample file on the CD that shows how it works. It's been a while since I had to do this, and I can't find the CD to refresh my memory, but it involves using a concatenated field, a relationship and a lookup. I took a look on databasepros, but couldn't find a techniqe file for it. I looked on fmfiles also with no luck.

So, the best advice I can give right now is that it's possible, but I don't remember how.

Sorry I'm not more help, but perhaps someone else here knows another good technique file site.

Hi

This is a bit tricky to explain so I have a demo file I just made to see if I could remember how to do this... and I did. So I will send it to you if your email address is there... if not let me know what it is.
