SQL "multi-part identifier cannot be bound" Error

I have to create a View that is extremely similar to another view expect for changes in Field Identifier values. I used the first as a template for the one I am trying to create. As per usual, I have looked at this thing a 1000 times and know there must be a disconnect or typo somewhere that I am not seeing.

I get the following two errors.

Msg 4104, Level 16, State 1, Procedure vPVTDetail, Line 2
The multi-part identifier "A379.EntityID" could not be bound.
Msg 4104, Level 16, State 1, Procedure vPVTDetail, Line 2
The multi-part identifier "A46.EntityID" could not be bound.
