ColumnA Column B ColumnC ColumnD
$2,958.73 Kelly RSP 5-Feb-07
$91,000.00 Sherri Non-Reg 12-Feb-07
$15,648.47 Kelly RRIF 21-Mar-07
These are my columns. I want to make a running total for each salesperson
PER QUARTER. So if their name appears in Column B AND Jan, Feb or Mar
appears in Column D, I want it to add their sales numbers from Column A to
this quarterly total:

Ex) Kelly appeared in Col B AND Feb appeared in Column D so it added
$2958.73 to her total quarterly sales:

Kelly 1st Quarter Sales $18607.2
