sort & report multiple criteria from multiple columns & report back a count to one ce

so for example - column "D" has 582 rows and each cell has 15 different values (1 to 9 and A to F) so i need to select all the instances of say the "C" of the 582 - now the tricky part i need to then have it tell me for all of the "C" values what is the "countif" total in the "M" column for only the "C" values. there are four possible values to count in the "M" column. if needed i can upload a sample of the sheet. also if it is something easy to duplicate for needing it multiple instances (15 of them like 5 times each) selecting the columns and then replacing the criteria would be best. sorry for the lack of terminology. anyone that can help i would appreciate it more than words can even begin to explain. Thank you. Abel.
