This is usually either because something has been missed out of the page type being used, or because of issues/clashes with JavaScript files on the page/s in question. It could be that there is a problem with one of the blocks you are using not sitting happily with another. A very common cause is that 'jquery.js' is being included more than once, and this will usually cause things to break.

First thing I would check would be to find out if there is a specific page type being used for the broken pages, and if so, check to make sure that it has the correct info included at the top and bottom of the file - ie the same as page types that do work.

If that all looked okay, it may be script related, you will need to try and find out the script that is causing the issue. Try using the Firebug addon in Firefox (Script tab) to see if/where things are breaking with your scripts.

Or, another way to debug is to remove files/addons one by one to see when the issue stops happening. This can help you find the offending script.

If you are unsure, maybe provide a link to your site here so that people can take a look for you?

One more thing, sometimes if you press ctrl+u (to view your page's source), you might see an error if there's one.

Thanks everyone, I will go to work and report what I find

Thanks everyone, the problem was caused by jQuery conflict.
Looks like when we were moving a utube video around we also got part of the script.
thanks
