I've a photo gallery with a navigation panel made of little buttons with numbers which, after clicking on them, load the relative photo on the right hand side.
This is the page: w w w.newtreedesign.co.uk/test/douglas/_test.html
When a number from the navigation panel is clicked, it should turn purple.
It all works fine in safari/mac latest versions but there are problems under IE/Win and FireFox/Win, the other 2 environments I'm keen to have compatibility.
Could please anyone suggest me what corrections I've to make on the code in order to be sure I've this compatibility issues sorted?
