As soon as I sent this I realized what was happening. It's testing for any occurence of 3 or more of ANY letter or number. So any string with 3 or more characters will always match.
Do I have to loop over each string and check character by character? <!----------------//------ andy matthews web developer certified advanced coldfusion programmer ICGLink, Inc.

Sometimes they (or their adults) type in values with long strings of one letter: ddddddddddddavid for example. I'd like to loop over the form fields and check for any occurrence of one character repeated more than 3 times. That should cover any legit instance. I'm guessing that this would be a cause for REReplaceNoCase, but I'm not certain what the regex would be. Anyone have input? For simplicity's sake, I'll just search for any letters or numbers. So I want to find any occurrence of 4 or more letters or numbers in a row. I was thinking that this should work, but it's matching whether there's 3 or more letters in a row or not: <cfset mystring = "waaaaaalt"> <cfif REFindNoCase("[0-9a-z]{3}",mystring)> hammer time <cfelse> nada </cfif> I'm using CF 6.1 <!----------------//------ andy matthews web developer certified advanced coldfusion programmer ICGLink, Inc.
