I'm hoping to make a formula where the average of sales for specific months is divided by the average of overall sales.

This is what I have so far:  

avg_if("TEST FORECAST SALES"."Month 2" = "TEST FORECAST SALES"."Month 2","TEST FORECAST SALES"."Total")/ignore_filters(avg("TEST FORECAST SALES"."Total"),"TEST FORECAST SALES"."Month"

But the issue is I am getting 1 as a result for all the months which I guess means that it's just taking the average for the months as well. How do I get the overall average?
