Welcome to the forum!
Absolutely nothing changes for each of individuals within the group? Not even a tracking number? If so, how would you distinguish them?
I would recommend using an unbound form with the text and combo boxes you mentioned. Add a button and the code behind that button would run an append query based on the number of iterations the user enters via a text box on the form.
The basic code in the on click event of the button would look something like this (air code, not tested). You will have to delineate values for text fields with single quotes and # signs for date fields. Numeric values do not need to be delineated.
Code:
dim mySQL as string
dim i as integer
mySQL= "Insert into tablename (field1, field2, etc) "
mySQL= mySQL & "Values (" & me.combobox1 & ", " & me.combobox2...")"
For i=1 to me.NameOfTextboxWithIterations
currentDB.execute mySQL dbfailonerror
Next i
