I have a cascading nav that starts off with 5 buttons, then off those buttons and each has its own, a row of buttons appears when 1 of the 5 is clicked.

All the buttons stay in view, so by clicking 1 of the 5 buttons its stays there as the next row appears, its so that the user can change their selection if they got it wrong, its a very simple information gathering nav.

What I wont to try and do is if one of the 5 is clicked it changes colour, but then if they got it wrong and choose another that new one changes colour and the other returns to its normal colour, and then the same for the next level.

I've included my navigation below, and I thikn this is a jscript issue rather than a CSS so thats why I'm posting here.

The interface is here and the log in details are there to just click enter, and then its the page after that splash page.
