Google Sheets, CountIf, name matches and is within date range from another spreadsheet

In another sheet I want to count how many meetings were scheduled for a rep within a date range.

My 3 columns are the date, rep, and misc data

=countifs(
"https://docs.google.com/spreadsheets/d/1q87c_0rFdt8FcWtIzD0KVW3k1ZpuvhfeWb1281MEs”,
”DEMOS!A2:C1000",
B2:B="Rep1",
A:A,">=11/9/2019",
A:A,"<=11/15/2019")

I'm a bit off it seems and I keep going around in circles.

Here is an example. I only want to count if Dates are between 11/9 and 11/15 and if the Rep is Rep1

A         |B
-------------------
Date      | Rep
-------------------
11/8      | Rep1
11/9      | Rep2
11/14     | Rep2
11/15     | Rep1
