Excellent, i understand all of that and now it doesn't seem like such a hard thing to do.

I've had so many attempts at this myself i'd kinda given up hope.

Thanks very much xcal. I'll have a look at the slider scripts again now and see if i can understand it more. The stuff to do with exportevars was a bit confusing to me but if i look at where it is in the script i might figure it out now.

Cheers
