Almost too embarrased to ask Antec sx830

[cats2cars]

Hello all.

I just received my new Antec sx830 case and most of the hardware has been transferred. One question however.
How do I attach the swinging door to the hindged section of the case? I could just be incorrectly assuming that it should attach. With my case whenever you open the door it pulls out from the hinged section.
Don't think too poorly of me as this seems to be beyond me at this time

its supposed to detach

Note: And man is this case heavy, i just moved from a Fong kai case: plastic everything except for the frame.
