Thanks Jason. That solved half of my issue. I keep mistakenly associating Y/N with Boolean but think I'll remember from now on.
My other issue was noticing once I change Boolean to text that the SQL was returning "=N" regardless of what the searched check boxes were. I left off the "S_" in the check field name. I new I was missing simple items. A hazard for a noob trying to retrofit after the fact.
Thanks again Jason.
