change the submit button to a regular button
<script>
funcion SubIt(){
if(document.formname.checkboxname.checked){
document.formname.submit();
}
}
</script>
in the button use on_click to call the function SubIt();
Any questions just ask

hai, thanks, but its not what i wanted.
when the form displays i need the button to be disabled by default. and when the user checks the accept terms and conditions checkbox, i want the button to be enabled.
if he unchecks the check box , we have to disable the button again.
thank you

That is what the script will do,,,if the box is checked it will aloow the form to be submitted, if it is unchecked, it will not be able to be submitted, you can make the button change colors or what not depending on if it is checked.
