I am constructing a Staff hours and wages sheet for a swim school. Each day
of a month has a column with a H/T (h=helping, t=teaching) column between
each day. This shows the hours a member of staff did on each day with
whether the hours were helping or teaching on each row. At the end of each
row I would like to total the helping hours and teaching hours separately.
I've tried using sum if but it doesn't like what I'm doing, an example of the
table is

Mon h/t Tues h/t Wed h/t Thurs h/t Fri h/t Total H
Total T
Ross 2 h 2 t 1 h 3 t 0
3 5

Any help would be much appreciated
