How to: Save differente repeater element to child table

HELLO.
​
I have a CF6 form with one group of "single use" fields and two groups of"repeat use" fields (using th -N- name notation).
​
I need to be able to save the data to 3 different tables: One Master Table for the "single use" fields and two Child Tables, with 1:M relationship from the Master table for the "repeat use" Child Tables and PrimaryKey->ForeignKey relationships to relate the data .
​
I cannot figure out how to do it, so all the help and pointers would be greatly appreciated.
​
Below is the array (as provided by debugger with some added comments by me so it makes easier to make sense of my array
​
Thanks is advance
​

Healyhatman, Super Help, thank you.
​
My array now provides me the following:
​
​

[Cadastro] => Array
        (
            [0] => Array
                (
                    [strCurso] => n
                    [strQualificacao] => No
                    [strAno] => No
                )

            [1] => Array
                (
                    [strCurso] => n
                    [strQualificacao] => Yes
                    [strAno] => Yes
                )

        )

No i just need some help in saving these items separately from the main data table....🤣
​
If you would be so kind

Loop event, data source {data:Cadastro}
​
Save event, data override set to

foreignfield:{var:save_data#.primarykeyfieldname}
strCurso:{var:loop_event#.row.field}
etcetc

HealyHatman, hello
​
Finally i managed to srt it out with your invaluable help.
​
I had to create a Save event to save the main data, with a Loop_Event inside the success and a Save event inside the loop event for the child data.
​
I have the following overrides:
​
strCurso:{var:loop_event20.row.strCurso}
strQualificacao:{var:loop_event20.row.strQualificacao}
strAno:{var:loop_event20.row.strAno}
strCpf:{var:save_data19.strCpf}
​
All working fine and dandy.
​
But.....
​
the content of the table is showing some question marks ( on some (NOT ALL) the fields. (the source for strCurso is a dropdown, but strQualificacao and strAno are both text fields, setup in exact the same way)
​

whereas the array:
​

Array
(
    [option] => com_chronoforms6
    [cont] => manager
    [chronoform] => frmcredenciamento-copy
    [event] => submit
    [strNome] => José
    [strend1] => 
    [strend2] => 
    [strCep] => 
    [strMunicipio] => 
    [strRg] => 
    [strCpf] => 999
    [strDob] => 
    [strEmail] => 
    [strCelular] => 
    [strFixo] => 
    [strCadastro] => Array
        (
            [0] => Array
                (
                    [strCurso] => yes
                    [strQualificacao] => Yes
                    [strAno] => Yes
                )

            [1] => Array
                (
                    [strCurso] => no
                    [strQualificacao] => No
                    [strAno] => No
                )

        )

    [button34] => 
)

Can u offer any suggestion?
