How would I do this…
For example if I had an input field and i could not allow the characters like \<\*\*space\> and ony \<\*\*underscore “\_”\> how would I do this??
I am guessing you would have to somehow check through ecach character to see if it was a " " with an if else statement… but that would take forever… so… =S
Thanks in advance… =D

[AS]myText.restrict = "^ ";[/AS] Where myText is your textfield insance name. This allows the user to enter any character except a blank space.
