    I am trying to create a difference amplifier with two sin voltage sources with 50mv pk-pk and 1kHz freq and one source 180 degrees offset from the other. I have calculated my resistance values and included a picture of my circuit. For some reason I am getting an extremely low value as the output and therefor the amplifier is not working. Can someone help me out Pspice is not my forte and I am trying to learn it. Thanks.

    It would appear your power supplies are set to 0V.
