Calculating Rate

[CS-TY26]

Hello!
First time poster here and fairly new to Power Bi.

I am working on creating a rate per 1000 days calcualtion. I have a category of infection and I am wanting to pull in a sub category, lets say "Bacterial" for this example.

I want to take that sub category, divide it by a count of days that a doctor would see patients (called residents x days- Q1 being 13064) then convert it into a rate per 1000 days. 

Any idea how to do so with this information or do I need to provide more? 

Thank you in advance! 

Ty

I can get you a better snapshot of the data if you need. I have been doing some research online and I have created this formula but it is not displaying any values when I try to put it into a number card for presentation. 

Bacterial Count Q1 =
DIVIDE(
CALCULATE(
COUNT('Infection Control Log'[Category of Infection]),
'Infection Control Log'[Category of Infection] = "Bacterial",
'Infection Control Log'[Fiscal Quarter] = "Q1",
'Infection Control Log'[Fiscal Year] = SELECTEDVALUE('Infection Control Log'[Fiscal Year])
),
13064
) * 1000
