Calendar layouts that link to appointments or events stored in a related table can certainly be created in FileMaker. Trying to describe all the details in a Forum format is a bit tough though. You might want to do a google search for calendars and FileMaker as there are some templates already created by others that you might want to take a look at to see how you might do this.
Thanks. I thought I had tried, but perhaps Calendars in plural made a difference...? Now I have something to go at.
Next questions: I find a lot of stuff made for FM7/8. Will that work?
