Encoders 3-6 Trouble

[Keo-san]

We are using three quadrature banebots encoders with divider kits in interrupts 2, 3, and 4 (we broke off one of the pins in 1 by accident). We are also using the standard Kevin encoder code. Counting for encoder 2 works with no problem but 3 and 4 remain at zero. I switched the encoders on 2 and 3 to see if it was an encoder problem and the same thing happened, 2 worked but not 3 and 4. I've looked around and interrupts 1-2 are different from 3-6 which need the Port_B so I think the problem might be related to that. Thanks a ton for the help!
