Obviously I'm not quite understanding, maybe a further explanation is needed to help me understand. This is how I see it from what you said - am in in the right ballpark. The function is returning a null value if there is no error, and I guess PHP sees 'null' or "" as a value. So how do I get around this? This is how I call the function. if($result = ValidateString($orgname, 1)) { $formerror['orgname'] = $result; } If there is an error an error string will be returned (i.e. Error in field), if not I want nothing returned. Later on in the page I use - if(!$formerror) blah blah. This is where the problem is because if null or "" is being returned then $formerror has a value which breaks the above if. I hope this helps.
