Password Validation/Confirmation

I've tried several ways to go about doing this, but I keep running into snags one place or another.

I have a CF 8 Flash form.  On this part of the page I'm making a form for them to request setting up an e-mail account.  In it's current form, the form does not load at all, this happened when I put the onClick into the submit button.  It has also previously happened when I tried an onsubmit in the cfform tag.  I hardly know anything about Javascript, and have been trying to piece together examples from out on the internet to get this to do what I need it to do. (Check password for 8 characters, must have special character/number, must input same password twice on the page).  I apparently can't use Spry because I'm locked in to having to use a flash form.

It's current form would meet all but the special character requirement, but as I said before, the form comes up completely blank at the moment, almost just like it does if you forget to name a field.  Can anyone shed some light into this behavior?

Here's the code, this particular form is just one in a tabbed page.

<script language="javascript" type="text/javascript">
    function checkPassword() {
      var strng  = document.emailSetup.mailPass.value;
      var strng2 = document.emailSetup.confirmPass.value;
      var errMsg = "";
      if (strng == "") {
            errMsg = "Enter a password.\n";
      }

      if ((strng.length < 😎 || (strng.length > 100)) {
            errMsg += "The password is the wrong length\n";
      }

      if (!/[0-9]/.test(strng) || !/[a-zA-Z]/.test(strng)) {
            errMsg += "The password must contain at least one letter and one numeral.\n";
      }

      if(strng!=strng2)
            errMsg += "Your passwords do not match!\n";
     
      if(errMsg==''){
            return true;
      } else {
            alert(errMsg);
            return false;
      }
return false;

}
</script>
