evalScripts: brought some help at least.

I'm still having two problems
1) two sliders appear on the website and both are functional
I assume there is a conflict between the initial render using with
and subsequent renders from the updater. But I can't quite get what
to do.

2) only the first slider gets updated on a regular basis and allways 
flickers when doing that. It seems that the whole div is redrawn 
everytime including the silder being in zero position initially.

This is the code I use (Counter is simply a global variable with
a value from 1-100):

Thanks,

Udo
