Function in Function in Qlik Sense

[lweny]

Hi all, I have small problem here with Qlik Sense since I'm really new to it. I'm going to count the total sales based on two fields, and I've written a script as below: =sum({$<[A]={"A2"}, mid([B],5)={"B2"}>}[Total_sales]) but it gives me error. Could you please point out the mistakes and make some corrections? Thanks.

It is the mid([B],5)={"B2"} that is your problem. You can only modify fields not expressions. You can look at set modifiers as invisible selections in your data model.

Try to rephrase your modifier so that you have [B] = {something}

The left hand side of a set expression criterion must be a field name, not an expression, so this does not work:

=sum({$<[A]={"A2"}, mid([B],5)={"B2"}>}[Total_sales])

You can probably use this to achieve what I think you were trying:

=sum({$<A = {"A2"}, B = {"*B2*"}>} Total_sales)
