Formula Based Data Validation 4 Date To Be Inserted

[Guest]

I want to put a data entry validation check for allowing a Account Maturity
date in B2 less than Now() only if the account balance in D2 is 0, otherwise
with a balance in the account a date only after Now() should be allowed.

Any suggestions & advices shall be highly obliged.

Thanx

Use a custom formula of

=OR(AND(B2<TODAY(),D2=0),AND(B2>=TODAY(),D2<>0))

and uncheck the Ignore blank checkbox.
