Using Relays in Code

[fred]

We ran out of speed controllers (our "genius" mechanics decided that we needed that many motors) and we are using relays and spikes right now. I am trying to use relays in the code and hitting some problems. Here is what I have now.

if(p3_sw_aux1 == 1){
relay1_fwd = 127;
relay1_rev = 0;
}

else if(p3_sw_aux2 == 1){
relay1_fwd = 0;
relay1_rev = 127;
}


else
relay1_fwd = 254;
relay1_rev = 0;

the p3_sw_aux1 part appears to work and the motor doesn't move when nothing is done to it. But we are having some problems with that p3_sw_aux2 part. Any suggestions or comments would be greatly appreciated.
