[Solved] Shipment plugin can't recieve checkout form data

[MikUrrey]

Hallo!
My shipment plugin generates some dynamic feilds in the checkout form. This fields must be used to calculate shipment price.
But I can not use its inside method getCosts because $_POST is empty, $_REQUEST don't contains this elements and JRequest::getVar don't returns right values.
What do I do?

[PRO]

do the fields have to be dynamic?

could they be fixes user fields?

[MikUrrey]

The fields must be dynamic but I can create user fields with similar names and replace its dinamically.
Will this make ones available inside the plugin method?
