Try this array formula** :

=MIN(IF((B1:B10<0)*(C1:C10<""),B1:B10))

** array formulas need to be entered using the key combination of
CTRL,SHIFT,ENTER (not just ENTER)

Please help me create a formula that finds the minimum non-zero amount in
a
column (B) based on the condition that there is a date in the adjacent
column
(C). Some cells in both columns will be blank (e.g. cells C2, C5 and row 6
is
blank). Example below should return result of $400 as the minimum in cell
E1.

Column A Column B Column C
1 item1 $1000 11/17/08
2 item2 $800
3 item3 $600 11/24/08
4 item4 $400 11/30/08
5 item5 $200
6

Thank you in advance for you assistance!
