Nested IIF or SWITCH Statement syntax needed correctly

Question

Can somebody please tell me what I am missing in this formula in SSRS? Or better yet can somebody please write this same thing in a NESTED IIF syntax?

Answer 1

Syntax looks correct at first glance. Most places in SSRS you are required to have = to start your statement. Your code above refers to embedded code for CalculateFraction() Does that exist and is it used successfully elsewhere?

Answer 2

Try using separated IIF Statements:

=iif(
    Parameters!StartMonth.Value <= 1 AND Parameters!EndMonth.Value >= 1,
    ReportItems!txtTotal2.Value, Nothing
    ) OR

 iif(
    Parameters!StartMonth.Value <= 2 AND Parameters!EndMonth.Value >= 2,
    ReportItems!txtTotal3.Value, Nothing
    ) OR

 iif(
    Parameters!StartMonth.Value <= 3 AND Parameters!EndMonth.Value >= 3,
    ReportItems!txtTotal4.Value, Nothing
    )
