JS error when "submit" clicked

[gcrighton]

Hi,

I'm getting an error displayed in the task bar when I click submit in a form (only when submit is clicked). The form processes and redirects as normal, and at such a speed that I'm unable to read the error type that flashes up.

Code I'm using is included below. Can anyone shed any light?

Thanks in advance,

Gary Crighton

// Declaring form
<form name=&quot;application&quot; action=&quot;/production/socio/suscribase2.php?lang=<?PHP echo $lang?>&quot; method=&quot;post&quot; onSubmit=&quot;return submitForms();&quot;>

// Sumbit code
<input type=&quot;submit&quot; name=&quot;submit&quot; value=&quot;<?php if ($lang == &quot;en&quot { ?> Next <? } else { ?> Siguiente <? } ?>&quot;>

// Validation script
<!--

function submitForms(){

if (lang == &quot;en&quot {

Error: 'lang' is undefined


Here's a debugging tip in IE: Go to:

Tools >> Internet Options >> Advanced

And check the box that says:

Display a notification about every script error


This way, every time you get an error, it will pop up right away.
