I've got another problem.

I have been asked to do some form validation on our site but the script I am using just refuses to work.

What I have done is, put the following javascript code into '/customer/home.tpl'

{literal}
<SCRIPT LANGUAGE="JavaScript">

function postit() { //check postcode format is valid
 test = document.registerform.b_zipcode.value; size = test.length
 test = test.toUpperCase(); //Change to uppercase
 while (test.slice(0,1) == " ") //Strip leading spaces
  {test = test.substr(1,size-1);size = test.length
  }
 while(test.slice(size-1,size)== " ") //Strip trailing spaces
  {test = test.substr(0,size-1);size = test.length
  }
 document.registerform.b_zipcode.value = test; //write back to form field
 if (size < 6 || size > 8){ //Code length rule
  alert(test + " is not a valid postcode - wrong length");
  document.registerform.b_zipcode.focus();
  return false;
  }
 if (!(isNaN(test.charAt(0)))){ //leftmost character must be alpha character rule
   alert(test + " is not a valid postcode - cannot start with a number");
   document.registerform.b_zipcode.focus();
   return false;
  }
 if (isNaN(test.charAt(size-3))){ //first character of inward code must be numeric rule
   alert(test + " is not a valid postcode - alpha character in wrong position");
   document.registerform.b_zipcode.focus();
   return false;
  }
 if (!(isNaN(test.charAt(size-2)))){ //second character of inward code must be alpha rule
   alert(test + " is not a valid postcode - number in wrong position");
   document.registerform.b_zipcode.focus();
   return false;
  }
 if (!(isNaN(test.charAt(size-1)))){ //third character of inward code must be alpha rule
   alert(test + " is not a valid postcode - number in wrong position");
   document.registerform.b_zipcode.focus();
   return false;
  }
 if (!(test.charAt(size-4) == " ")){//space in position length-3 rule
   alert(test + " is not a valid postcode - no space or space in wrong position");
   document.registerform.b_zipcode.focus();
   return false;
   }
 count1 = test.indexOf(" ");count2 = test.lastIndexOf(" ");
 if (count1 != count2){//only one space rule
   alert(test + " is not a valid postcode - only one space allowed");
   document.registerform.b_zipcode.focus();
   return false;
  }
alert("Postcode Format OK");
return true;
}
</script>
{/literal}

I have as you can see I have changed the form object model variables to co align with the form.

I then added this in on the actual register form for customers '/customer/main/register.tpl ':

{if $js_enabled and $usertype eq "C"}
{include file="buttons/submit.tpl" type="input" style="button" href="javascript: return check_registerform_fields() + postit();  return false;"}
{else}
<input type="submit" value=" {$lng.lbl_submit|strip_tags:false|escape} " />
{/if}

But it keeps coming up with this error in FF v3:
Error: missing } in XML expression
Source File: http://mydomain.com/register.php?
Line: 24, Column: 1
Source Code:
test = test.toUpperCase(); //Change to uppercase

It works in normal html as such, with the following criteria for a successfull postcode validation script:

1. The total length must be 6,7, or 8 characters, a gap (space character) must be included
2. The inward code, the part to the right of the gap, must always be 3 characters
3. The first character of the inward code must be numeric
4. The second and third characters of the inward code must be alpha
5. The outward code, the part to the left of the gap, can be 2,3, or 4 characters
6. The first character of the outward code must be alpha

Can someone help please?

Thanks ever so much,
Jeremy.
