List "Totals" Calculation Problem.

[Cognos_Jan2017]

Hoping the attached Excel file retains formatting.  Attempted formatting below probably won't retain when this is Posted.

In the example file, cannot get "Overall Totals" Row to Calculate properly.

      All Calculations in Cells C11, E11, G11, and I11 are Correct                  
      The Property Data Item Summary is set to "Calculated"

37   311   88.10%   155   50.16%   119   61.74%                   = Row 11

      All Calculations in Cells C12, E12, G12, and I12 are BAD                  
                        
   Suggestions how to get Correct calculations in Cells C12, E12, G12, and I12                     
                        
   TIA, Bob

Overall Totals is easy, after some thought ...

Unlocking the "Totals" Cell, then ... writing a Query Calculation of something like ...
(Total([HowManyLocs])-Total([< 1 Year]))/Total([HowManyLocs])

... and adding that to the Cell, then Locking WORKS fine.
