i have a spreadsheet containing:
employee, date, qty of errors, comments

it contains many rows if inputed information in order by date inputted
(sorted by date) employees are listed each time they issue a document. This
spreadsheet is tracking how many errors they make on these documents.

i need to calculate: 1) number of times each employee is entered, 2) Average
error per each document per person, 3) average error per document for all
employees as a whole.

Can anyone help?
