Ramon, You mentioned originally that all fields are required. If they are required, than using CFParam is making them non-required by giving them a default value. or... did I misread your statement? reading it again, I think what you are saying is... for an age field example, you have <cfparam name="URL.Age" default="-1" /><cfif URL.Age EQ -1 ><cfset errorMsg = "Please enter a valid age" /></cfif> is that right? well, this isn't anything too terribly wrong here... It's a bit backwards than the way I would approach it, but it does seem to take care of the basics. this, in combination with the information Aaron posted below, will help to make your forms bulletproof.
