If you really want to do this with javascript...

Looking at the agree_with_paypal.htmlpage source, see that you have 
created two forms - they should be combined into one form. Also, here's 
an alternate code snippet, think you may be hung up on trying to grey 
out the superfluous button. Not tested, but should give you enough of an 

function checkCheckBox(f){
if (f.agree.checked == false )
alert('Please read/accept terms to submit form');
return false;
return true;

<formaction="https://www.paypal.com/cgi-bin/webscr" method="post" 
onsubmit="return checkCheckBox(this)">
<input type="checkbox" value="0" name="agree"><b> I agree to the above 

<inputtype="hidden" name="cmd" value="_s-xclick">
<inputtype="hidden" name="hosted_button_id" value="8NGJU6BFETY32">
border="0" name="submit" alt="PayPal - The safer, easier way to pay 
online!"><imgalt="" border="0"
