I would like to sum up a column of agent commissions using a range of
dates.
For example: the agent has input all of his commissions for january 1,
2006
through april 30, 2007. I would like a sumif formula that sums up the
commissions for just the year 2006. Is this possible with sumif? I have
tried using = and <= but it doesn't work.

Thank you, Ricky
