The formula is not pulling all data. Below are the formulas I am using:
Overdue: =COUNTIFS({Status}, "In Process", {Assigned to}, "Susan Hacker", {Current Completion Date}, <TODAY(0))
Due in 1 month: =COUNTIFS({Status}, "In Process", {Assigned to}, "Susan Hacker", {Current Completion Date}, <=TODAY(30), {Current Completion Date}, >=TODAY(0))
Due in 3 months: =COUNTIFS({Status}, "In Process", {Assigned to}, "Susan Hacker", {Current Completion Date}, <=TODAY(90), {Current Completion Date}, >TODAY(30))
