Recyclable package checkbox ignored

[bitclick]

Hello, I'm having problem with the recyclable and gift wrap checkbox on 1.6.1.6. They are ignored when placing an order, no matter what I check.

The strange thing is that they work with OPC but not on 5step checkout. And they both use the same order-carrier template.

So I'm lost on where to look at to fix it. I assume, since it works in OPC, that the checkbox value is not brought to the last order confirmation page (but it's just a guess).

Also the templates are basically the same as default, just some appearance changed (I'm not sure it even works on default template actually, I can't revert to default or i lose all the block/module customizations).

Any suggestion?
