Playhouse Ladder and Railing

Today I finished the ladder to get up to the loft and started the railing.  The stairs took me longer than it should have because I messed up on the spacing of the steps.  I didn't realize the problem until I had two steps left to install!  The basic frame for the railing is up, but it's still shaky, and I need more lag screws to secure it to the loft.
