Thanks..I'll let you know
Eric, Thanks for the pointers. I am out of town now and will try this later in the week. I am not sure how I can test that only 6 out of 10 radio buttons are "on" or how they are able to choose other than the first radio as the their first choice, but I'll look at your example. Glad to hear that I can use the built-in validation. I was starting to cobble together a Javascript check for this---and I really don't code Javascript!
