I have a question:

I have a worksheet that in one column contains the dates of the reports were
generated and in another column text codes (example: 1-UCF, 1-DEL, 1-HOM,
1-PAS, 2-UCF, 2-DEL, 2-HOM, 2-PAS).

My question is, how do you write the formula if you want to count the number
of codes that have the prefix 1 that occured on January?
