I have the same problem as this guy:

Can anyone care to help an extreme novice at fixing this?

It sounds like you need to adjust your water level. The tank usually has a mark on the inside back of the tank that's way below the handle. If you have a float ball ballcock you can lower the tank level be bending the floatball rod down until you reach the desired level. Good luck, Tom

Like the previous person who had this problem, I do not habe this float ball.

What do I do?

I think you have a fluidmaster 400 ballcock, is it gray with a black top with a cup on the side hanging on a stainless wire?? If this is right let me know and I will tell you how to repair it. It takes a very cheap part to make it like new.

TO lower the tank level lower the float can by the clip on the wire. Good luck, Tom

I replaced the fill valve and that fixed the problem. Thanks everyone for your assistance.
