Your output transistor has no base bias voltage and the input signal level is too small to turn it on.
If it is biased properly then it will be an amplifier.
True but how do I change 100mV to something that will turn on my second transistor
Hi all
I need to square up this sine wave and using another transistor to do so.

Are you trying to convert this sinewave to a squarewave?
An LM339 has four comparators in a 14-pins package. But an LM393 has only two of the same comparators in an 8-pins package. I didn't look at the costs.It would be a lot easier with far less parts to just to use an LM339 comparator to convert the sinewave to a square-wave.
