Table one Table Two
StudentID >--< StudentIDInfract Relationship between the two tables
To expand on Davidander's suggestion, you DO want multiple records, but you use a separate related table of infractions liked by a studentID number. You can use a portal to infractions to see and edit a student's infractions so you may want to look up "portal" in FileMaker Help.
Thank you, gentlemen! As soon as I recover from the day I will give it a try.
