Using a COUNTIFS formula with a less-than criteria

[nj167252]

Below is the table I am working with. The "Call Sequence" column is just a continuous list of Calls (1 to 2221). There are 11 different call types with 11 corresponding Prefixes. Because there are many calls of the same Call Type I would like to count them. I also want to have the "Suffix" represent the latest total number of that specific Call Type.

So, for example, row 02214 has a Prefix "MX," I want the suffix of that row to show "001." And on row 02221, which also has a Prefix "MX," that suffix should show "002." When I use a COUNTIFS formula (=COUNTIFS([Prefix], [@Prefix],[Call Sequence], "<=[@[Call Sequence]]"), it shows "0" as the result.

Any help is much appreciated.

For < or > operations, the criteria needs to be written like

"<="&[@[Call Sequence]]
