Form Javascript Verification

[Arsenal]

My goal is to make it so if the check box is checked, the page continues as normal. If the checkbox is not checked, then the page is redirected. I don't get any syntax errors but the code does not do what it is intended. What am I missing?

 

 

<script language="JavaScript">
			function check_agreement(){
				if(document.getElementById('term_agreement') == false){
					window.location = 'index.php';
				}
			}
		</script>
		<form name="registration" enctype="application/x-www-form-urlencoded" method="post" action="index.php?PHPKatalyst=register&step=user_info" onSubmit="check_agreement();">
		In order to proceed, you must agree to the following <strong>Terms & Conditions</strong>:<br /><br />
		<fieldset stlye="font-style: italic;">


		</fieldset>
		<label for="term_agreement"><input type="checkbox" name="term_agreement" id="term_agreement" />If you agree to these <strong>Terms & Conditions</strong>, then check this box.</label>
		<div style="text-align: center;"><input type="submit" value="Continue" /></div>
		</form>
