Jump Problem

after alot of work i finally got my character to jump perfectly but now the problem is that whilst my character is in the air i can click again causing it jump again in the air and i do not want it to do that. how can i fix this?
this is my rule: when game.jump is true - timer for .08 sec - accelerate up with a 3500 speed.

simply have a rule when attribute jump is true
change attribute self motion linear y to 300
and to answer your questions, to get rid of the double jump simply put the rule i just told you in another rule whne actor collides with ground, so you cant jump once your in the air till u touch down again
