how do i sum a row of vallues based on the condition that the text value in a
dropdown box in a row above it. for example

a b a d a d a total-a total-b total-d
1 1 1 1 1 1 1 4 1 2

the letters are a row of drop down boxes whose values can be text. i have
in the drop down boxes types of leave (annual, sick, famil, etc). at the end
i have totals for each kind of leave.
