First, I'd go to Filemaker's download site and get the free update to Filemaker 10.03--it fixes a few bugs.
Do you know how to set up different tables in filemaker and link them in relationships?
Do you know how to set up a portal? (You can look this topic up in Filemaker's help system to learn more.)
You can place a payments portal on that last tab to log each student's payments.
You can then create a report based on the portal's table to get the "end of the day" report you describe.
Thanks for the heads-up on the update.
I just got filemaker two days ago, so I'm still learning the basics. I have figured out how to calculate an age automatically with a birthdate and how to set up basic forms with basic tables. That's about it so far. I'll have to really look into linking relationships and portals. Thank you for your help! At least I know it's possible now :)
