Prevent entry based on another cell value

Hi every one
A1=5
B1=10
If C1 is is not between 5 and 10 then D1 is "locked" for entry.
I suppose some sort of custom conditional formatiing would do this but Im
not sure how to do it.
Thanks!
Melissa

Melissa,

Select cell D1, then use Data | Validation, then choose "Custom" and use
the formula

=AND(C1>=A1,C1<=B1)
