This pong code does not work

Xela

So I'm doing pong for a project we are doing in school in processing, but with my code the player's bars keep changing size when I change location! Can someone help me please? Thanks!

//SINGLE PLAYER PONG

//Directions:
//Try to hit the ball back every time.

//UP or W to move your paddle up, DOWN or S to move your paddle down.

In the rect() for your left paddle, the height of the rectangle should be constant, not change with mouseY. Try changing mouseY - 175 to just 75.
