Case 2: If Card 2 is the first card, you will get the following result:
Evaluation # B A Result
1 3 1 4
2 2 1 3
3 1 1 2
4 3 2 5
5 2 2 4
6 1 2 3
7 3 3 6
8 2 3 5
9 1 3 4
If both A and B are contained in the same card object, evaluation sets are selected
based on the order A and B appear in the rule. Leftmost objects are selected first.
If you change the rule to look like
NumberSet ( s ) = B:Card2 + A:Card2
the same results are produced as shown in Case 2 above.
Functions Influence the Number of Evaluation Sets
For this example, you have the following rule
NumberSet ( s ) = A:Card1 + SUM ( B:Card1 )
Using the same values for A and B, there are only three evaluation sets.
This is Evaluation Set 1:
A Values B Values
1 3
2 2
3 1
