I have a word in a different cells on a row in my spreadsheet e.g.

Mon Tues Wed Thur Fri
Hoovering Nicola James
Washing up Steve Lisa

etc

I would like to know a formula that could add up the amount of names that
have been allocated for a certain task, and that would automatically change
if a name was added or taken away, so i can have a "total" column in a
different cell elsewhere in the spreadsheet telling me how many people there
are.
