I need help with a SUMIF formula that is needed that adds the amount based on
one condition but excludes another.

Example:

A B C
Prsn Type Contracts
1 JG MP $8000.00
2 JG DV $1200.00
3 JG MP $10000.00
4 SA AF $6000.00
5 SA DV $4500.00
4 JG AF $3000.00
5 JG DV $1500.00

I need it to calculate the total contract amount for all of JG's, except for
the types marked as MP.

Any help would be great.
