Hi Jinx
if using Data Validation to create your drop down list the easiest way is to
range name column F in sheet 2
(go to sheet 2, click on F, click in name box (left hand side of formula
bar) type name (no spaces), press enter)
then click in Sheet1!A13, choose Data / Validation, choose List - click IN
the big white box, press you F3 key to bring up list of names in workbook,
choose the name, click OK, click OK again and it should work fine.
Hope this helps
Cheers
