How to check if a string contains a number?


I have a variable that is being set in coldfusion.  What I need to do is to somehow check If the variable contains numbers or only letters. So for example if the variable is HHIEU88HDKJS, I need something that know there are numbers in there and returns a value of True.  If the variable is NUUIENDIIE, I need it to return with false.

Thank you
