And my experience with the check every bad value approach is that it is time consuming, produces ugly code, and I invariably miss some character or another.There are a couple of ways to accomplish what you want.One way is to create a conversion database which converts a-z, A-Z and 0-1 to nothing. Then set a temporary text variable to the value of the form variable. Pass the temp variable through the conversion db above which would leave everything in the string except alphanumerics. Then if the size of the temp variable is not zero, they made and input error.___Joe___ _________________________________________________ Joseph D'Andrea JoeDan@West21.com WEST21.com Internet services for the 21st Century http://www.west21.com/ _________________________________________________ ------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list .
