Why does Jbutton disappear after click?

[INeedHelpASAP]

I am trying to make a program that opens a panel that contains a JButton. When the user clicks the JButton it is supposed to redraw the Jbutton to a new random position on the panel. There is also a counter on the Jbutton so that i can messure how many times the user has clicked the Jbutton.

My problem is after clicking the JButton it disappears off of the JPanel and can no longer be clicked. Is there anyway i can set the randomization of the Jbutton to fit the panel? Sorry its unorganized and all over the place.

Why do you have add(gameButton); ?
Try removing that.
