air.fall not working?

[Master0fFaster]

Trying to make a move to juggle with only if it hits the opponent in the air, but apparently air.fall isn't preventing anyone from teching out.
It's not a matter of juggle points, the move has juggle=0.
I'm not sure what the problem is, is there another part I'm missing that would affect this?
If possible I'd like to make it so the opponent doesn't get knocked down from it, but I need that juggle.

That's the problem, air.fall is to knock out the opponent if is in the air, so if you got it activated then I doubt you can connect anything.
The solution probably has to delete that line in HitDef or put air.fall = 0 to get the opponent not to be knocked out with the move and so make the juggling with your combo
