Validating form

[Praetorian]

I'm writing a script to validate an email address, and it's giving me a headache.I can't for the life of me figure out why this block isn't working...

var the_dot = document.frm.user_email.value.indexOf(".");if (the_dot == frm.user_email.length -1){			alert("Your Email Address is Invalid.");			frm.user_email.focus();			return (false);		}

Umm... if indexOf() cannot find a character then it will return -1, so if you are checking for a period's existance your function will be

var the_dot = document.frm.user_email.value.indexOf(".");if (the_dot == -1){			alert("Your Email Address is Invalid.");			frm.user_email.focus();			return (false);		}

I actually already have a block performing that function. What the problem block is supposed to be doing is making sure that there are characters after the period. Which is why I'm confused. Because if the index of the dot is -1 of the email's length, then isn't it the last character in the line? Making the email invalid? Yet that block I wrote always without giving an error.

we forgot the .value property

if (the_dot == frm.user_email.value.length -1){

Gah. I'm stupid. I remembered to add it to the var part, but forgot to add it to the function. Sheesh. Thanks.
