I've been doing nothing but confusing myself today...

I am building on a previous report which should display in the header mm/yyyy based on a parameter date starting from 12 months ago. Below each month should be a count of tickets closed per user.  My first column should be the assigned usernames.

I understand how to show each month based on the prompt date entered

ToText (DateAdd ("m", -12, {?Close date}), "MM/yyyy")
ToText (DateAdd ("m", -11, {?Close date}), "MM/yyyy")
ToText (DateAdd ("m", -10, {?Close date}), "MM/yyyy")
etc

And from my other report I know how to Sum the amount of tickets per user

if DateDiff ("d", {cr.open_date}, CurrentDateTime) in 121 to 150 then 1 else 0  then creating a Summary (SUM) of this formula.

But for some reason this is not computing (in my head) to show the count of tickets per month based on my enter date parameter.

Any thoughts to point me in the right direction?
