battery

So today my car got stuck at work simply because it would not start. We tried jumpstarting it it cracks for a second then gives out. When starting without the cables it clicks then shuts off. If you have any advice please come my way!! Thanks in advance.

I own a 1994 3.8L Ford Mustang, manual transmission. Recently replaced my red positive battery cable with a new black cable. I left my lights on today and ran the battery dead. I have a battery jump starter, but like a moron I connected the cables backwards due to the black positive cable...
