Cant get clutch pedal to go down while car is running. 99 boxster
 

I have replaced the clutch master and slave already since the slave was leaking (while slave was leaking i was able to drive and go into gears just fine) after replacing them and bleeding them my luck broke another slave trying to press pedal down, slave number 2 is in now and same thing after bleeding system clutch pedal works fine while the car is off but as soon as i turn it on the pedal only gos 1/4 way down and wont let me go into 1st gear, 2nd kinda but then again while trying broke yet another slave cylinder. 1 person told me to just do a full clutch swap yet i cant afford that at this time and i need my car for work since this is my daily transportation.

Sounds like something inside the clutch is broken/bent and preventing the clutch from disengaging completely which is why the pedal won't go all of the way down. When you force the pedal down, too much pressure is placed on the slave cyl and it breaks because something inside the clutch is stuck.

Sorry, but you're most likely going to have to remove the trans and inspect the clutch assy next.
