replaced clutch on 2007 hyundai tuscon and now car wont move in any gear and shifter feels sloppy -l

[glennp]

I replaced the clutch , pressure plate and throwout bearing. Now the car will not move in any gear or reverse. Also the gear shift feels sloppy, like it does not click into gear it is kinda vague and loose. Any idea what this could be, could the throwout bearing have fallen off when I lined up the splines to the engine.....help
