Glad it helped. I can't even remember how and where I stumbled across that... allowed me to do a TON of client side automation on forms. Probably NOT the best solution, but in specific areas, it works well...

I have done pretty much the same thing. I ended up using a little jscript. I call it with the "true" or "false" that I want the item to have.

function applyvalidate(myenableflag) {
document.all.validate.disabled = true;
if (myenableflag == true) {
document.all.validate.disabled = false;
}
if (myenableflag == false) {
document.all.validate.enabled = false;
}
}

The name of the button is "validate". I do this so that the person has to have a valid form (actively check with jscript) and when it is valid, the validate button lights up. they can then hit the validate button that provides a code for entry into a checklist. Then I light up the submit button. At anytime when the formcheck becomes invalid, i use the same functions to disable the buttons on the fly. Does that help?
