double gamemode

in my game i have game mode such as the character can jump higher, but when that game mode happens twice in a row the character can then jump really high. it adds the number twice, so instead of adding 4 it will add 8. Please help me make it so the number wont keep getting higher higher when you have the game mode multiple times in a row.

Try a toggle switch where your jump force is and make sure loop is not selected.Screenshot (2)

thanks for your help @Fier, should i have it loop or not and should it start at 1 or 2, also i dont know if a toggle with work because its on and off high jump, in no specific pattern.

can anyone help with this?
