Warehouse Kit - Stair from outside to door?

[yojeff]

So I made a big warehouse with the Warehouse kit, but I can't seem to connect stairs to the doorway?

With the wood building, I put the fondation block, then the wall with the doorway, and the wood stairs connects to the doorway.

I used the warehouse floor with the warehouse doorway, and I'm trying to connect the warehouse stairs.

Thanks!
