The regex itself was not really the problem, although I appreciate the help
on that, but I'm not sure I follow the rest of what your saying. I tried
your line below, and whether or not there were errors, an error was always
returned. So ABC or @#$ would give me the same result.
if ( ($result = ValidateString($event) ) !== false ) {
$formerror['firstAttempt'] = $result; }
Thanks
