I am attempting to generate dynamic column charts based on grouped data in a
separate sheet.  The user selects the data, and after putting the sheet
together, the chart needs to graph This Year and Last Year as separate
series, but use only Country, Region, and Unit, no sub-Unit
I am looping through the rows, and putting together the string to assign to
.Values for each series, but with a change to the structure of the data, now
I am getting a much too long string to assign to .Values (255 char. limit)

The basic string for the first series that I get from my loop is 308
characters.
strSeries1 =
"=Summary!$E$14,Summary!$E$15,Summary!$E$16,Summary!$E$23,Summary!$E$24,Summary!$E$27,Summary!$E$31,Summary!$E$35,Summary!$E$38,Summary!$E$39,Summary!$E$45,Summary!$E$46,Summary!$E$48,Summary!$E$52,Summary!$E$55,Summary!$E$56
Summary!$E$58,Summary!$E$59,Summary!$E$61,Summary!$E$62,Summary!$E$64,Summary!$E$65"

I have tried assigning the first cell to the .Values property and using
.Extend, but that has not worked for me either.  I have checked out every
conceivable site that i have found, and yet nothing has worked.  Please
Help!!!

The data on the Summary sheet is basically formatted as follows:
    A                    E                         F
                      Last Year            This Year
Country            
Region
Unit
   Sub-Unit
