Car won't start----PLEASE HELP

What is your question?

Let me begin by saying this is my first place to go for advice. This morning my car started up fine, after stopping at a local business my car would no longer start. I was able to get someone to give my a jump. I placed the jumper cables on and the vehicle stared up, but once I removed the cables (with the car still on) the car turned off..... I don't have a local dealer that I trust here in Milwaukee, WI. Help what should I do. Should I try to give the car another jump? I feel that I may not have left the cables on long enough. WHat kind of problem does this sound like? Thanks nin advance for your trusted help.
