I am trying to build a Teacher/Student Schedule where the teacher may have more than 1 student, the student may have more than 1 teacher, and both may have more than 1 subject to schedule. The schedule must have date and time entries built in certain blocks of 1 hour each before noon and 40 minute blocks after noon. Any suggestions or tips would be helpful. The tables I have so far are for teachers, students and subjects. Thanks, Ken
