After flushing.. The small tank inside the tank fills up.. But the water doesn't shut off- just runs continuously. How do I stop it?

This is the one with the tray inside? It too has a float. It is either not adjusted properly or is bad. Lift the float arm and see if the water stops running.

It was not the float.. there was an insect leg caught in the little pump thing that shuts the water off.. how the insect got into my water line I have no idea.. lol but its fixed.. Thanks
