validation works in IE not Firefox, why?

I have the page where if you leave everything blank and click submit in IE and error box shows up, in firefox it ignores the validation and submits the page. why? making me crazy!!

It was your main function that was screwing up ....... you were trying to access the style with things like logError.style.visibility without using document.getElementById .. try this ..... works fine in both now!

function validateForm() {
	if(document.getElementById('logError').style.visibility == "hidden" && document.getElementById('pwdError').style.visibility == "hidden" && document.getElementById('rePwdError').style.visibility == "hidden" && document.getElementById('emailError').style.visibility == "hidden" && document.getElementById('birthdayErr').style.visibility == "hidden")	{
		return true;
		}
	else {
		alert("There is missing or invalid data on the form");
		return false;
	}
}
