1994 Honda Civic Clutch Problems

I just replaced my Clutch Slave Cyl. due to leaks and loss of pressure from my clutch pedal.

I replaced it now I cant get any fluid to run into the slave cyl. and there is still no pressure on my clutch pedal.

Im looking for help on why there is no fluid running into my slave cyl.

Could it be the master cyl. ?

Or is there another problem or the master cyl and another problem?

Please help!!
