Count instances that happen within time range

Okay I have a workbook with multiple sheets. On each sheet is a list of service calls. The time a service call is received is formated as General ex "02:05:00". I want to count how many times a service call is late between hours of the day ex 00:00:00 - 01:00:00 , 01:00:00 - 02:00:00 and so on. There is a column next to the service call received time that will have "Late" in it if the call was late. I have tried a few different formulas but just can't get it to count them.

This is the most recent formula i have tried (obviously i would have to add the "Late" criteria but even without that it wont count).

=COUNTIFS(CAO!$X$21:$X$500,">="&TIME(2,0,0),CAO!$X$21:$X$500,"<"&TIME(3,0,0))
