Frame Base Jump Loop

I have a problem with my frame based jumping loop. It does the check every frame to see if the vertical axis is greater than 33%. Then it checks if the axis is being held down. It then executes the Jumping function which is supposed to keep the frame on which the jump is activate and then see is the current frame is equal to the stored frame plus 4. If that is the case then add to the vertical velocity variable which is later added in LateUpdate().

My problem is, is that check[1] is true on every frame so it sets my current frame to the newest one every time so the player never jumps. What I need is for check[1] to be done once so that it will store the correct frame and then jump 4 frames later.

     int[] curFrm = new int[64]; 
     bool[] check = new bool[64];
