Import from form - Repeat Children

Hello!

I’m followed the tutorial for shopping cart using Data Store and all is working fine, except the check out part, where I need to record to the database the data from data store.

Below, my checkout page, where I show the cart content, complementary fields and a hidden repeat with the data from my shopping cart:

Now, I would like to insert a “order” to my database table + order details (cart data).
Before create all all the steps, I need to define my posts variables, importing from the checkout form, but the “repeat” doesn’t import as an array and I can’t use Multi-Insert Query:

What am I missing?

Thanks!
