This code currently does not do anything different when the button is pressed. You want the motor to run at half speed or half the speed that the joystick commands when the button is pressed? The following assumes that you wanted the first option.

The 0.5 constant in the case statement is not connected to anything.

For the false case of each case block the joystick axis value should pass through the case block.

For the true case the 0.5 constant should be wired to the small orange block on the right edge of the case that will appear when you wire the joystick value through the false case.
