I have this big old worksheet that links up and adds from four other worksheets. All the cells from 3 of 4 of the worksheets are collected in the master worksheet in a typical cell like: =+'P:\ROAD MAP\2011 Working Roadmaps\[Working RoadMap2011 Carla.xls]WorkingFcst'!AE16

But in one little section of the sheet, all I see in the formula which IS pulling the data from one of the other 4 sheets like the example above, all I see in the cell is:
=+'[Working RoadMap2011Heather.xls]WorkingFcst'!AE17

Why is the second example NOT showing the full file path like the first example? I need to live and die by these numbers and I am not comfortable with these mystery formatting whereby I can't be sure where the data is coming from other than seeing that when I change the numbers in the source file, I see the changes in the target file?
