Hi
to do this you need to give the range on the other sheet a range name
(select the data, click in the little box to the left of the formula bar and
above column A and type a name - no spaces and press ENTER).
now return to you other sheet - select the range where you want the drop
down box, choose data / validation - choose list, click in the source line
and press the F3 - your range name should be displayed, selected it and
press OK and it should work fine.
For more details on using data / validation - check out Debra Dalgleish's
