jquey cluetip and CodeIgniter

[eluser]Aidy[/eluser]
Hello all

I'm trying to use the jquery cluetip plugin with CodeIgniter. I'm would like to get the tooltip to display some content via ajax. I can get it working fine with a standard html or php page but as soon as I request a page from a controller there seems to be a problem and the tooltip displays 'sorry, the contents could not be loaded'.

I have had a look at the cluetip plugin file attached but have no real understanding of jquery or ajax.

Can anyone help? - Thank You
