I have a file i'm using to calculate invoices and totals, in the summary
page i want to create a month by month summary

i have read the excel help and i cant find what i need, I am using the
DSUM function to calculate a running total which works fine.

eg: =DSUM(C$14:G$1015,"Amount",C$1:G$2)

but how would i get my sheet to add all the invoices together revcieved
in one month if all the dates appear in one column???

and then combine this with my DSUM function to split the incoices into
the relevant cost centres???

thanks in advance for any help... this forum has saved me hours of
headaches and rage outbursts!! It rules!!
