Okay, so my slave cylinder was leaking and I would lose pedal if I held my clutch in so I bought a new one, took the old one off, put new one on and now I can't get it to get any pedal... I don't know what to do and have to be at work in 3 hours lol HELP!

Whenever I pump it it starts to get a little pressure but there are no bubbles or fluid or any movement at all in the fluid reservoir on the master cylinder...
