You might compare your script to the example found here: Scripted Find Examples
You could also set up your check box field as a match field in a relationship and use Go to Related Records to pull up the matching set of records instead of a find.
WOW!!!! the GTRR WORKS! I thought it didn't but i had an old script triggering on layout enter that only found one list. SO much more simple. THANKS PHIL!
