yea a supreme solution!
i've added the script but i got a little error message when ordered the
first product..
looks like interchange needs the "#COUNTER-1.0" at the top of
etc/order.number
ive replaced the line in reset_order_number:
print ON strftime("%Y%m%d0000\n", localtime() );
to
print ON strftime("#COUNTER-1.0\n%Y%m%d0000\n", localtime() );
now it works perfectly.
thanx all
mike
