I have two columns:
H J
Date Quarter

The both columns have a validation: Date is checking that entries
should be in the date format; Quarter is linked to a list of quarters
and checking that the entry is from that list.

However, I'd like to have some checking between these columns as well
for the dates matching with quarters. E.g., if Date is 1/1/2005 in H2
the user should choose only Q1 from the list in J2.


Alex:

Don't let them choose if there's only one choice. Put a formula in J to
calculate the quarter:

="Q"&CHOOSE(MONTH(H1),1,1,1,2,2,2,3,3,3,4,4,4)
