Isn't the template you want to edit called [signupadult] and not [registeradult]?? [signupadult] is where you read the rules.
Also, your directions were very sketchy.. the parts that are being copied in are not found in the same area within the template... I had to go all over my code looking for bits and pieces so that I didn't have multiple nested forms.
Thanks for the template mod though, this will help force my members to read the rules for once.
