This is a complicated procedure you are trying to accomplish. In order for the DB to perform the request there will need to be proper table design. Relations are key here so you have a WAY to write the code.
Reading your question in post #1 raises concern that your table structure may not be what it could be. You may be working harder than need be. In fact, the solution you seek and the route you are considering as a solution may be the product of poor design.
I would start by rethinking why you need to duplicate records. You may not need to. However, even if you do not need to duplicate records you will still need to understand how to query the results you desire from the tables. So, catch 22. No way around not knowing how to code.
You can start with researching a CASE statement. You present a scenario where a user says something. In the CASE they say, "4", you need to pass that value to the program. Once the program has the user's input stored in a variable, you can begin doing something with it.
In your case I may start by declaring a variable that the program can store the user's input in.
Code:
Dim intUserInput as Integer
Here I imagine an intuitive name to name my variable and assign the data type Integer to it. This example is not addressing related issues to data types and validation and truncated values.
Now I can pass the user input to the declared variable.
Code:
intUserInput = Me.txtUserInput.Value
The example assumes the user is typing data into a text box named txtUserInput within a form.
Now you can apply a CASE statement to determine what to do with the user input.
Code:
CASE Select intUserInput
Case "2"
[Insert statement that does something twice]
Case "4"
[Insert statement that does something four times]
Case Else
MsgBox "The data base does not like your Input"
End Select
I suggest you play around with collecting user input and doing things with said input. You can build your own practice data bases to explore, IF THEN ELSE and CASE SELECT statements along with a MsgBox response. If this is something you feel comfortable with then you might want to do more exploring.
