You can query "the thumbpos of sb xyz"...

thumbpos = thumbposition
sb = scrollbar

Less typing :-)

Or if you like response in "realtime" while dragging the slider,
put this into the script of the scrollbar/slider:

on scrollbardrag the_value
    put the_value into fld 1
end scrollbardrag

This message "scrollbardrag" is send continuously as long the user
drags that thing :-)

And there is one parameter "the_value" (or call it whatever you like)
that will hold the current value/thumbposition...

Hope that helps...
