Need help getting repeater area in email

I'm trying to make a form in which you can add a drop-down's to choose something:

The goal is to add as much of them as you need. This works, but I can't get it to email all the line's, just the last one.
I'm sure it's something with array's or loop's, but I don't get it...
Who can help me?

Hi Robbert,
​
If you use a Repeater area make sure that the input names end in [] to make them array names.

If there are multiple inputs per group, I like using group[index][field] notation. Like
​

order[{var:area_repeater#.key}][qty]
order[{var:area_repeater#.key}][item]

Using field1[ ] and field2[ ] as the names
​

    [field1] => Array
        (
            [0] => a
            [1] => b
            [2] => c
            [3] => d
        )

    [field2] => Array
        (
            [0] => a
            [1] => b
            [2] => c
            [3] => d
        )

​
Using group[{var:area_repeater#.key}][field]
​

    [group] => Array
        (
            [0] => Array
                (
                    [field1] => a
                    [field2] => a
                )

            [1] => Array
                (
                    [field1] => b
                    [field2] => b
                )

            [2] => Array
                (
                    [field1] => c
                    [field2] => c
                )

            [3] => Array
                (
                    [field1] => d
                    [field2] => d
                )

        )
