Where is problem?

This is becuase you are writing jumpSpeed + hiz;, This will return a value but the value is not being used so it is pointles if you did jumpspeed = jumpspeed + hiz that would work or as Kam said, use jumpSpeed += hiz;

jumpSpeed += hiz;

You can not declare an assignment that way> jumpspeed + hiz; You can only declare assignment: increment, decrement, call.

jumpSpeed += hiz;
