Excel CountIf, plus second statement

I have two columns of data, please note not all rows have data inputted (i.e. Row 1 could have data in Column 1&2, Row 2 has data in Column 1 but not Column 2, and Row 3 has data in Column 2 but not Column 1, etc.).

Column A is text holding provincial acronyms (2 letters such as AB, SK, BC, etc.), Column B is Accounting with $.

In my other table, I want to COUNT Column B IF there is a $ value but only count if Column A equals a certain value (ex: AB).

Example, COUNT cells in Column B where $ is greater than 0 IF the corresponding Row in Column A equals "AB
