set analysis value

[felcar2013]

hi

i have two variables:

let vTest2 = max(month_ID)

let vTest = fieldname (numeric,1,2,3,4 ...12)

in TextBox, this works: $(vTest2)-$(vTest)

but in set Analysis no

=num(Count({$<month_ID ={"=$(=month_ID)- $(vTest)"}>}distinct customer_id),'#.##0')

i want to deduct both variables, how should i do this?

thanks

felipe

num(Count({$<month_Id={"=max(month_Id)-$(vTest)"}>}distinct customer_id),'#.##0')
