Hello,
I posted info here regarding validation expressions:
http://www.dnncreative.com/Forum/ta...fault.aspxI haven't tried this, but the first thing I would do is when you create your list in the host menu - for the 'Select an Option' give it a numerical value - ie. 1
Then in the validation expression get it to check for alphanumeric values, if it sees a number it will not allow the form to be processed.
- This is a guess, I wanted to give you a starting point as I'm going away for a few days.
If you find the solution, can you post it here for everyone to read, thanks,
