I have created this image map http://www.omegadm.co.uk/aureos.com/our-funds/

If you rollover one of the areas of the map a box pops up with a text box and a link to another page.

What I now need to do is when the user rolls over a region the same text box pops up, but it has a number of other links they can choose.

I am really stuck on how to do this, does anyone have any suggestions on how I can achieve this? - Deadline looming!
