Aaron,
The following array formula will return the minimum value from C3:C13 where
the corresponding entry in B3:B13 is equal to the value in cell C1. If the
value in C1 is not found in B3:B13, the result is #N/A.
=IF(COUNTIF(B3:B13,C1)=0,NA(),MIN(IF(B3:B13=C1,C3:C13,FALSE)))
This is an array formula, so you must press CTRL SHIFT ENTER rather than
just ENTER when you first enter the formula and whenever you edit it later.
If you do this properly, Excel will display the formula in the formula bar
enclosed in curly braces { }. See
http://www.cpearson.com/Excel/ArrayFormulas.aspx for more info about array
formulas.
