I am trying to create a formula that will project how many times someone will place a call over the course of a month and over the course of a year (as examples), given their historical calls placed over the work days that have passed in a selected period.

 

Generally, this is what I was thinking would be a good way to calculate it (in layman's terms):

 

 

Because I want to include the user's unique "selected time horizon" (ie a month, or a year), I think I will also need help creating a parameter.

 

If someone could help me with this, I would be eternally grateful

Thank you ahead of time!
