Hi Diogo,
probably the best way to achieve what you want is to use an array with 6
sub-array (array[6][12]).

You can declare your array in the MainView, doing something like this:

property var arrayInt: [[], [], [], [], [], []]

Then, whenever a user insert a value in a TextField, you can save it:

onActiveFocusChanged: {
    if (!focus) {
        arrayInt[0][0] = text;
    }
}
                                                                                }
changing the index of the array following your needs.
At the end, when you want to calculate the result, you can use the array.

Of course you can use id to access value, but using an array is IMO easier and
less messy.

Regards,
