IE Error on Page 'elements.zone_id' is null or not an object

[limelites]

Hi all,

 

I'm new to this forum, but hopefully someone out there can help.

If you look at my login page in Internet Explorer then you'll see I'm getting an Error on Page:

 

'elements.zone_id' is null or not an object

index.php Line:38

 

I checked my page source and line 38 is this:

if (!theForm || !theForm.elements["zone_id"]) return;

 

I've narrowed this down to this file: includes/modules/pages/login/jscript_addr_pulldowns.php

 

I've tried commenting out some of the script but the error then just moves around until eventually I get an error: object expected.

 

I'm hopeless with javascript, so I'm really hoping that someone out there can help me fix this?
