Data Validation

[Jamal]

I have data validation on two sheets of a single workbook. On one sheet the
dropdown list appears when the cell is selected. However, on the second sheet
the dropdown list does not appear. I have checked the "incell drop-down"
option for both sheets. Infact I have been using this workbook for a while
and it worked until I allowed others to work on it. The data validation has
not been deleted. How can I solve this problem? Thanks for your help.

If you delete the row that contains the cell with the problem data|validation,
then insert a new row in its place (and put back all the other info on that row
as well as add the data|validation), does it work ok?
