Still submitting form after alert 1

[snowboardr]

I can't get this code to stop the submit if the error occurs, do you see whats wrong? I have it the function run on onSubmit="CheckTheFile();" and it is showing the error message

Jason

function CheckTheFile() {
	if(document.frmSend.attach1.value=="") {
		alert("Please click browse and find the ad you would like to upload.");
		return false;
	} else {
		if((document.frmSend.attach1.value.lastIndexOf(".jpg")==-1) || (document.frmSend.attach1.value.lastIndexOf(".gif")==-1) || (document.frmSend.attach1.value.lastIndexOf(".tif")==-1) || (document.frmSend.attach1.value.lastIndexOf(".png")==-1)) {
			alert("File types accepted : jpg, gif, png, or tif");
			document.frmSend.attach1.value="";
			return false;
		} else {		
			return true;
			document.frmSend.submit();
		}	
	}
}
