Code error?

[niagra127]

Alright our team has been trying to run a motor through a pwm with the buttons on the joystick.

if (p1_sw_aux1 = 1 && p1_sw_aux2 = 0)
	{
		pwm10 = 255
	}
else if (p1_sw_aux1 = 0 && p1_sw_aux2 = 1)
	{
		pwm10 = 0
	}
else
	{
		pwm10 = 127
	}

This returned nothing on the motor and we are positive the motor runs.
We also tried just using pwm10 = 255 to see if anything would happen and we got absolutely nothing in return. The motor just constantly sits there, we think its an electrical problem but we are still getting told its a programming error. If this is true can anyone tell us what it is we are doing wrong?
