First step of debugging, always: Confirm your assumptions. You assume exportRoot.Mark exists. You assume exportRoot.APDHMIDM exists. Confirm this is true. Stick some console.log() statements in there that display them.
It turns out that exportRoot.Mark was mis-Instance named as b_Mark which was the problem.
Looking at the line in question I assumed the issue was APDHMIDM since I would surely never make such a stupid mistake as not naming my button selection marker correctly... which is exactly what happened.
