Adding cancel button in my Javascript : Is it possible to add a cancel button in this javascript so the form will not be submitted?
This Javascript is currently working in validating these form fields but if for some reason I entered a wrong information there is no way for me to cancel and prevent the form being submitted.



	<script language="JavaScript">

	function validate(form)
	{

		if (form.Institution.selectedIndex == 0)
		{
		  alert("You must select an institution for any necessary future correspondence.");
		  return false;
		}
		if (form.Requestors_name.value == "")
		{
		  alert("You must enter your name for any necessary future correspondence.");
		  return false;
		}
		
		if (form.EntityFirstName.value == "")
		{
		  alert("You must enter the Entity's first name.");
		  return false;
		}

	  alert("Your form has been successfully submitted!");
	//  form.reset();
	  return true;
	}

	</script>
