Multiple IF(AND) Statements

I am attempting to calculate a commission based on the range that the number falls in between. I keep getting a #value error.

C1= $15
C2= $1,000,000
C5= $0.00
D5= .75%
B6= $.01
C6= $15.00
D6= 2.00%
B7= $15.01
C7 = $50.00
D7 = 2.50%
B8= $50.01
D8= 3.00%
This is the formula that I have
=IF(C1<=C5,C2*D5),IF(AND(C1>=B6,C6<=C1),C2*D6),IF(AND(C1>=B7,C1<=C7),D7*C2),IF(C1>=B8,D8*C2,0)
