i need a formula that can tell me the last time that a client placed an order
w/ my company

all of our clients place multiple orders with us over the span of the year,
and many clients names are in the workbook. the formula needs to be able to
countif the name of client if correct and then sort the dates that client has
ordered- (another column) to provide the most current date

something like countif j1 - j200 = joe's bakery & then sort g1-g200 for the
most recent date.
