Mike, thanks for that code. If I can't get that to work I'll just get what I need with a separate form. Bruce, what I'm trying to get is a phone number in the PayPal flow of my web store checkout. I don't get a phone number back from PayPal using ExpressCheckout. I'm not using the Save button because I like the buttons being in the tab box with the other fields and text in a nice line, there is more than one, and they are primarily GET'ing another page, with the PayPal API call first thing in those pages. I wanted to require the phone number entry on the next to last page after I have the buyer details from PayPal, right before they confirm the details and click the PayNow button which calls a page to notify PayPal of the sale and display the order confirmation number. I figured the required attribute didn't work there because the PayNow button does a GET back to the server, and it didn't look like I was getting the phone number anyway, required or not. So I may just have to do a Form that PUT's to get what I need. Thanks for all the help.
Brian
