Hi again,

Try 'doing' only one action first, then call that function several times.
If that keeps returning a '1' then this doesnt work, but you cant
do 5 or 6 or more things and call it 5 times and expect to see
a different value returned unless you did something different for
one 'do'.
Like i said though, if this doesnt work it's not my fault 
but it's worth a try.

If you solve it another way you're now obligated to tell use what
it was 


Take care,
Al
