Sorry, forgot... The reason that I choose not to rely on updating manually is simply because out of more than 350 million people, there's bound to be a few that may apply to our organization and not check off Additional Racing Classes and then submit the incorrect fee with the membership application...

Excellent! Thanks for all your trouble and time.Form works great!

OKay, just had time to try out the calculate(). It didn't work. I tried applying it to chkMST-ARC, no go. I tried applying it to MT10, no go. I tried applying it to each of the classes, no go. I also tried using the path technique, still no go. Please help.

How woul...

Paul, Thanks for your time. I'm just having one problem. The dollar amounts are not changing. If I check off Non Racing Membership the three bellow go invisible, which is great, and it's corresponding textfield is giving a value of $15.00. If I uncheck it the three bellow reappear, which is great, b...
