Hi,

Would love some help with this challenge.

Accident data is being recoded in a spreadsheet and has info recorded for 12
month. In a separate tab I want to count the number of instances by a given
month, then by a given department, and then by accident type. Have used
three separate "countif" statements and can get the number of accidents for a
month, the total number for a give department for 12 months, and the total
number by accident type for 12 months. I want to be able to get the total
for a month, by department, then accident type.

Hope someone can help me, thanks.
