I have a form on which I am doing some verification and if the verification fails returns the same form with fields already filled in where possibe using REQUEST. One road block that I've run into is a set of checkboxes that I have. My verification script can deal correctly with them regardless whether or not it's sent a list, and string, or nothing it all. In passing back to the calling form I thought I'd do something like use url_quote to pass REQUEST something like:

myForm?list=%5B%27checkbox_1%27%2C%20%27checkbox_2%27%5D

Eek! Erk! Yuk! Don't do that ;-) More helpfully: The above if very fragile and unsightly. Rather than doing a redirect to get back to your form, just return it at the end of your validation script, should the values not be good enough: return context.myForm() ...that way you'll still have the original request and won't need ot do any nastiness to pass values around. cheers, Chris
