Hi, please help me! 

How can I get next rezult?

{A} - {B} = {D}

1. I have attached a QVF with working example

2. Set Analysis formula can be done between 2 alternate states like this: 

Concat( { <Field=P({'State 1'})> - <Field=P({'State 2'})>} Field, ', ')

3. Here is a post with a complete hands on Set Analysis workshop if you want to go deeper. 

4. Go to Master Items to create/see the Alternate States
