Lid impossible to lock down RESOLVED

I have a brand new Cuisinart Custom 14 cup food processor (out of the box yesterday. In attempting assembly, I am unable to lock the lid to the work bowl. I’ve watched the Utube videos, and I’m pretty sure I’m doing it correctly. However, this is the second machine I’ve had. I returned the first one for exactly the same reason, thinking it was defective. Now I’m not so sure. HELP !!!

Note: figured it out. Feed tube goes in the back, not in the front like most processors.
