I'm using Excel 2003 w/ SP2 and have encountered a problem I don't recall
having before. I have a workbook where a summary sheet is used to aggregate
the values in each of the cells in the rest of the sheets by using a formula
with following syntax:
=sum('sheet1:sheetx'!Cn),
where "sheet1" is the name of the first sheet in the range of contiguous
sheets, "sheetx" is the name of the last sheet in that range, "C" is the
pertinent column letter for a cell (the columns in this workbook represent
years) and "n" is the pertinent row number.

When I insert a new column (for a new year) in the supporting worksheets and
then copy an existing column in the summary sheet (with the above formulas)
and insert it in the appropriate location in the summary sheet so that it
will refer to the proper column in the range of supporting sheets, the
formulas refer to the new column but the results don't reflect the sum of the
values in the new column. The results reflect the sum of the values in the
column from which the formulas were copied. If I simply hit (F2) and enter,
without changing the formulas, they will then produce the proper results.
However, it seems to me that i shouldn't have to do this. The formulas are
correct without editing them. Why don't the show the proper results
automatically? I've experimented with manual vs. automatic recalculation and
with iterations to no avail. Anybody have any ideas? Is this a bug?
