I have a sumif formula situation that is killing me.

Column C, D, E, F, and G all have ranges of numbers divided into groups (5
rows to a group). I have 6 groups total. Every row after each group has a
row that adds all the numbers for that group.

A1: Name
B1: H
C1: 100
D1: $1000
E1: $2000
F1: 50
G1: $5000

I need a formula that will allow me to add columns C, D, E, F, and G based
on whether or not it has a "H" in B.

I tried:
=sumif($C5:$C52,"L",D48:D52,D37:D42,D26:D31,D16:D2 0,D5:D10)

but there are too many groups, after D37:D42, it says I have too many.
