1) Script Title: Dynamic Ajax Content

2) Script URL (on DD): http://www.dynamicdrive.com/dynamicindex17/ajaxcontent.htm

3) Describe problem: I'm fixing a website for a client and came across one problem that I can't seem to fix. The script was added by another developer and any help in decoding this will be appreciated. The website is currently in a close beta stage but the script is below, it works fine in firefox but not in IE. IE gives an Unknown runtime error on this line:


document.getElementById(containerid).innerHTML+=page_request.responseText;
