Hope I'm in the correct place.

When I preview my (unpublished)website in IE8, I get this on every webpage:

I checked out the code on ddtabmenu.js and it looks like this:

//DD Tab Menu- Script rewritten April 27th, 07: http://www.dynamicdrive.com
//**Updated Feb 23rd, 08): Adds ability for menu to revert back to default selected tab when mouse moves out of menu

//Only 2 configuration variables below:

var ddtabmenu={
disabletablinks: false, //Disable hyperlinks in 1st level tabs with sub contents (true or false)?
snap2original: [true, 300], //Should tab revert back to default selected when mouse moves out of menu? ([true/false, delay_millisec]

currentpageurl: window.location.href.replace("http://"+window.location.hostname, "").replace(/^\//, ""), //get current page url (minus hostname, ie: http://www.dynamicdrive.com/)

What do I do to correct this problem? Thanks a lot (in advance!) for the help.

Moving from Java to Javascript.

},

In several locations, syntax error. Remove the commas.

Javascript statements should end with a semi-colon ; (but not after a })
