Formula debugging help

[Mikeyis4dcats]

Can anyone point me to the error in this formula?? I'm going crosseyed!

=((IF($C$4<=500),23.50,(IF($C$4<=2000)),((($C$4-500)/100)*3.05),IF($C$4<=25,000),((($C$4-2000)/1000)*14),IF($C$4<=50000),((($C$4-25000)/1000)*10.10),IF($C$4<=100000),((($C$4-50000)/1000)*7),IF($C$4<=500000),((($C$4-100000)/1000)*5.6),IF($C$4<=1000000),((($C$4-500000)/1000)*4.75),((($C$4-1000000)/1000)*3.65))

Try:

=IF(C4<=500,23.5,IF(C4<=2000,(C4-500)/100*3.05,IF(C4<=25000,(C4-2000)/1000*14,IF(C4<=50000,(C4-25000)/1000*10.1,IF(C4<=100000,(C4-50000)/1000*7,IF(C4<=500000,(C4-100000)/1000*5.6,IF(C4<=1000000,(C4-500000)/1000*4.75,(C4-1000000)/1000*3.65)))))))
