I am working on improving the "Lunar Lander Program." I am trying to make a flame appear beneath the ship when I push the down button. The flame appears and then I use VBSrcInvert later in the code to say "If the down key is pressed then invert the flame." This makes it look like just one flame is beneath the rocket. When I let off the down key, It leaves just one flame beneath the rocket.

Please Help,
