Hi everyone! I'm trying to build monthly employee attendance with NFC tag. Basically when you "scan" nfc tag with your phone, it open up AT Form for submitting your entry or leave (start in the morning, start of the break, end of the break and end of work). In this form you can choose what type of entry or leave you're submitting. Name is preffiled (and linked to another table with personal information about

Of course, when submitting the form, every entry from the form is in a new record. Is it possible to combine all four records into one (for one day)? And after that, I want to calculate duration (how long was one working and how long was on break). I tried by updating the field in another table, but I don't know how to define where (to which record) should information update (so for the specific employee and for a specific date).

I'm thinking to build specific table for every employee.
Can anyone help me?
Thanks!
