I could be wrong, but I think when you put the ^ inside of the []'s that you are saying not the following characters. So basically you are saying if the string does not contain alphanumeric characters. I could be wrong though, its happened before. Jason Stechschulte jpstech@nc.edu Hey, Here's an easy one for someone to field. I do these regex validations in just about every piece of code I write with forms, so I'm a little baffeled why it doesn't work, cus it looks good to me. if ($name=="" || eregi("[^a-z0-9\.-][[:space:]]", $name)) { print "ERROR, Please fill out this field, and use alphanumerical characters only!"; } Basically if the field is left empty or contains anything but alphanumeric hypen period or space it should print the error message. However, entering something like !@#$%^&*(+_* passes right through the regex.. no error message is displayed. Whats the prob here? Thanks. Jason
