ok, first of all, thanks mike. second of all... how do you handle this then? i have a set of checkboxes that i want to get the value on the next page, via cfml. i also want them to be able to be checked as well as unchecked. and on my subsequent page, get to all of them. if i make them all the same id, then i can get them in a list from the form.fieldName, value.
how would i do this same easy thing without the same id/name? tw On Mon, Feb 9, 2009 at 3:35 PM, Michael Grant <[email protected]> wrote: > > ...or you could just loop through it like I said.
