VW Golf - window won't do up?

I have a VW Golf 1.9 TDI 2002 and yesterday when I went to do up my passenger window it made a crunch noise. I put the window down again and then it wouldn't go back up and now when you pull the electric window leaver up it makes no sound. I really can't afford to pay out loads of money to get it fixed but when driving to work this morning the window started to fall down slowly and I am now worried about driving the car but need it for work. Can anyone help
