Need to Validate Working of Participation and Rate Eligibility Formula

Hi,

We created a Participation and Rate eligibility fast formula to validate eligible benefit plan for a particular employee. There are 5 parameters (Gender, Nationality, Grade, Place of Issue (Visa) , Number of Children), which were fetched via value sets in FF itself. We compared these values and could not validate eligibility of benefit plan itself. Please help in this requirement and steps to resolve the same.
