hey aaron... 2 thoughts:
1. if those three fields are not unstored calculations they can be used to define a multi-key relationship and then you could simply use the count function to return the number of related records.
2. alternately, you could make a script in which you would enter find mode, set the value of those fields as needed (empty, "no", and "1"), perform find and use the get ( foundcount ) function to give you the count of qulaifying records. you could then either temporarily display that value in a custom dialog or set a field to the found count value to display this count.
and i'm sure there are other ways too... hope that is helpful.
