If and alternate states

[Priya10]

Hi all,

I have an expression as below, which works perfectly fine.

count({Target<Billing_Period=$::Billing_Period>}distinct Matter_InvoiceNum)
+
count({Reference<Billing_Period=$::Billing_Period>}distinct Matter_InvoiceNum)

but as soon as it 

wrap the same expression in if or pick match it does not work.

kindly help me with this issue.

Hi, it will be better if you post a sample of the expression wrapped, what it returns and what you expect. Even better if you can upload a sample to work with it.
