Problem with Form?

[updw123]

Hi there,

I've really not had much to do with this before, but I've been trying to convert a form for use by a local charity and it appears just not to work:
http://www.p-s-i.org.uk/temp/email.html

If anyone could help I would be grateful.

Many thanks,

The function you're using is as follows:

function PostCodeInSwindon() {
// code here something to extract the first (non-blank) four characters of the postcode
postcode=document.getinput.postcode.value;
postcode=postcode.toUpperCase()+'      ';
postcode=postcode.substring(0,4);
InSwindon=false;
// check for those postcodes in Swindon
switch(postcode) {
    case "SN1":
        InSwindon=true;
        break;
    case "SN2":
        InSwindon=true;
        break;
    case "SN3":
        InSwindon=true;
        break;
    case "SN4":
        InSwindon=true;
        break;
    case "SN5":
        InSwindon=true;
        break;
    case "SN25":
        InSwindon=true;
        break;
    case "SN26":
        InSwindon=true;
        break;
}
// display the processed postcode
getinput.processed.value=postcode;
// display a different result in an input box depending on whether the postcode is in Swindon or not
if (InSwindon) {getinput.result.value="Swindon"}
else {getinput.result.value="Not Swindon"}
// call a different file depending on whether the postcode was in Swindon or not
if (InSwindon) {destinationpage = "swindonemail.html" + "?Swindon"; top.location.href = destinationpage }
else {top.location = "noemail.htm"}
return
}

and it's called here:

<FORM NAME="getinput" onSubmit="PostCodeInSwindon(); return false;" enctype="text/plain">

One problem is that it should be:

onsubmit = "return PostCodeInSwindon();"

Another is that getinput is not global: you need to use document.getinput to refer to the form.

Yet another problem is that you've got 4 characters from the postcode, but you're only checking for 3 (for most of the cases in the switch statement).
