Cross Checking Info with VLookup and Extracting Data from sheet

So in my excel document I have it such that on the first sheet (Labeled 'Sorted') the data is set up as follows:

LOCATION, EXTENSION, NAME

With the appropriate data under each header. On the second sheet (Labeled 'Locations_Ext') I have a named range called Locations; it contains extensions from a separate document, names of people associated with the extensions from the document, and their locations on the map. I am trying to have it such that the excel matches the extension number given on the first sheet with the ones that I extracted from the document on the second and output the location into the first column on the first sheet. The code I have set up for that process is:

=VLOOKUP(B(//SomeValue),Locations,1,FALSE)

I then want the excel to cross check the information that I took from the Visio to see if the visio is up to date with the latest info we have received (Which is the data on the first page under Extension and Name). The code:

=IF(C(//SomeValue)=VLOOKUP(B(//SomeValue),Locations,3,False),"Good","Error")

Both codes seem to be giving me this: #N/A as the results for every cell.. What am I doing wrong? I'm using MS 2010

It would be better if you upload a sample workbook with enough sample data in it along with the desired output filled manually.
