It would seem that I should be able to backscan for two rules in combination, that is, to test for those bars when both rules are met, but I have not been able to get accurate results. Both rules were set to buy at the next day open.  The trade-based rule was to exit at the open the day after the buys were entered.  I have tried all possible priority combinations of Buy for Rule 1, Buy for Rule 2 and the trade-based exit rule set to 0 days, but none yield accurate results.  What am I doing wrong here?

Dragging and Dropping Rules into BackScanner is not an AND type way to combine things. It is an OR type way to combine things. BackScanner goes through the Rules starting with the highest Priority Rule (the one at the top) until it finds a Rule that returns True or makes it through all of the Rules. At the first Rule that returns True, it Executes the Rule and then goes onto the next Bar.

If you want to combine Rules in an AND type fashion, you will need to Drag and Drop the Rules (the actual Rules that are outside of BackScanner) onto each other and select Create New Combo Rule. You can Drag and Drop more Rules into the Combo Rule and you can use either ANDs or ORs in between the component Rules making up the Combo Rule.

Once this is done, you can Drag and Drop the Combo Rule into BackScanner to use as a Rule there.
