What I want to do:
+------+--------+---------+-----------+----------+--------+-------+------------+| Week | Monday | Tuesday | Wednesday | Thursday | Friday | Total | Difference |+------+--------+---------+-----------+----------+--------+-------+------------+| 1 | 8 | 8 | 8 | 9 | 8 | 41 | 1 |+------+--------+---------+-----------+----------+--------+-------+------------+| 2 | 8 | 8 | 8 | 8 | 8 | 40 | 0 |+------+--------+---------+-----------+----------+--------+-------+------------+| 3 | 8 | 8 | | | | | |+------+--------+---------+-----------+----------+--------+-------+------------+In the above table, I want a formula in the 'total' column that will only sum the values from Monday to Friday when all five cells contain a value. If any of the cells are empty then it shouldn't sum them.How can I do this?
