just to be sure: you have stack A where you want to do something on all 
cards and
stack B, where a progress-bar should display the progress of these 
actions ?

OK, here we go:

on xxx
    put the number of cds of this stack into tCards
    put the long name of sb "le_progresse" of cd x of stack "B" into 
le_prog
    ## this put something like "scrollbar id 1003 of cd id 1004 of stack 
xxx" into the var,
    ### so you can refer to it with just a single word ;-), makes not 
much sense in this
   ### example, but you get the picture...

    set the endvalue of le_prog to tCards
     ## so you don't have to count before ;-)

    palette "B"
    ##or whatsoever...

    repeat with x = 1 to tCards
        set cursor to busy
        ### so you have this nice spinning beach-ball

        set the thumbpos of le_prog to x
        ### set the progressbar
        ### do your card-stuff here
        ### if possible, do NOT go to cd x, this will speed up things 
heavily :-)
        ###  my script : go to cd x ...
    end repeat
    close stack "B"
end xxx


Hope this helps.
