Q: Problem Trackpad Macbook pro

My trackpad on my Mac Book Pro isn't really responding to my touch.

It starts spazing out and does it's own thing with it's own movements (clic, creating files, closing, moving around...)

I can't even move it.

I can't do what i want to do...

I can't anymore use it... i have to use an USB mouse to be abble to use my mac book

Is there anything I can do to fix this?

Thanks for your help
