Firefox issue with Javascript in VB

[greentips]

I have some issues with Firebox with the following modification to the "postbit_legacy" template. I am using VB 3.8.2.

Specifically, when a user uses "quick reply", the browser only displayed the banner and cannot refresh to bring the user back to the appropriate updated page. The entry to the db is actually made, a browser refresh will bring the screen to the proper update. There is no issue with using "advance reply".

I am using a javascript to create a rotating banner using the code here: How-To-Show-A-Banner-After-The-First-Post-In-A-Thread

I have insert the following javascript to the line for the banner:

<!-- Banner Rotator -->

<SCRIPT LANGUAGE="Javascript"><!-- 
function banner() { 
}; 
banner = new banner(); 
number = 0; 
 
// bannerArray 
banner[number++] = "<a href='http://www.xxx.com target='_blank'><img border='0' src='/forum/xxx.gif'></a>"
banner[number++] = "<a href='http://www.xxx.com target='_blank'><img border='0' src='/forum/xxx.gif'></a>"


 
increment = Math.floor(Math.random() * number); 
document.write(banner[increment]); 
//--></SCRIPT>

<!-- End Banner Rotator -->

Please point me in the right direction to figure out how to solve this issue.

Thanks
