How to enable and disable a submit button with a check box?

How guys,

i’m not sure the title helps, but all I wanna do is force users to agree to terms of service by checking a few check boxes before they can submit the form. Much like during the Revo install. The submit button should be disabled unless and until those boxes are checked, which means the users agreed to the terms.

I’m using MODx Revolution RC1. Any help would be greatly appreciated!

Cheers,

would be pretty easy with jquery.
