That will solve the 'illegal input' problem very effectively once and for all ...You can probably take another approach to solve this problem, too. For example, maybe you can do some math on the value entered to determine if it is a number or some letters. Perhaps simply by dividing the entered value by 1 would make WebCat2 respond with either a number or nothing. I haven't tried this but it's easy to test and may be worth a try ...There may be even better ways to do this. One thing I have learned is that there's almost always a way to do something with WebCat2 ... :)Sincerely, Ken Grome WebDNA Solutionshttp://www.hui.net/dna/webdna.html Associated Messages, from the most recent to the oldest:
