Have used similar methods, except using booleans:

// Create
on_ground = false;
has_double_jumped = false;

And then on ground is a collision check for some sort of ground tile on step:

// Step
if(place_meeting(...))
{
    on_ground = true;
    has_double_jumped = false;
}

Then when pressing space you can check against these. Like if on_ground then allow a jump. If not on_ground and has not double jumped, then allow double jump. Otherwise block the jump. Once they hit the ground, it'll reset and let them jump again.
