Okay that's good to know that I'm have at least a loose grasp of what's going on.
The one other thing I can't quite figure out is how you were able to first div content to show up by default.
I thought the loop for the divs hides the divs as long as the variable 'i' is less than the 'sel' variable's length so how is the first div content visible by default?
Thanks a lot for indulging me in this by the way.
