How to convert to Ligo type

Question

I have this smart contract and was wondering how to convert to a ligo type

transfer
parameter list($transfer_item)
transfer_item pair
   from_ address
   txs list($txs_item)
txs_item pair
   to_ address
   token_id nat
   amount nat

Right now it's set to

type transfer_destination is record [
  to_             : address;
  token_id        : nat;
  amount          : nat;
]

type transfer_param is record [
  from_           : address;
  txs             : list(transfer_destination);
]

type transfer_params is list(transfer_param)
type transferType is TransferType of transfer_params

and Im using transferType but It does not seem to be working. Im guessing it has something to do with txs_item is a pair and its listed as a record.
