"Multiple Tries" Question

Basically you use the "Contains" condition to check for the desired pairs. Clear a counter. Have one action for each starting point - i.e. 1-1, 1-3 are valid put those on the condition tab and if any are true add 1 to a counter. Then do the 2-... and add another to the counter. At the end, test the counter for how many ever matches there should be.
