We have a workbook with seven columns of data and which
may have varying rows of data depending on the month's
data being captured.

A B C D E F G
1 xx 3
2 qq 4
3 dd 2
4 ww 5
5 ee 8

We are trying to include in our macro a routine that will
go to the first blank row below the data and enter the
word "Totals" in column A. Then we want to enter the sum
of each column (B through G) under each column on the same
blank row as the word "Totals." In the above example we
would enter "Totals" on row 6 in column A and then 5 would
be entered on row 6, column B. 12 would be in row, column
C. etc.

We got this far with the macro but couldn't figure out how
to get the sums entered.

Range("A1").Select
Nmrows = Range("A1").End(xlDown).Row
Cells(Nmrows + 1, 1) = "Totals"

TIA for your help.
