Yea thanks I will look into it in more depth soon, I've got a client who is "eager" to see some progress so unfortunately for now I'm just focusing on getting an example working.
I've got a div with an ID of "textcol". I also have a few buttons that change the content of textcol when they are clicked, this part is working perfectly.
As for the code that looks about right, thanks for your help. Would it be better to put the onMouseover on the actual anchors or is there any way I can have the JavaScript loop through all the ID's...
Basically I have a load of anchors (over 100) and I also have a small div that needs to be populated with unique text each time one of the links is clicked.
