building a multisig transaction using RPC I´m trying to build a multisig transaction using RPC. Till now my code looks similar to this:

At first I get the unspend outputs calling listunspend()

With those UTXOs I´ll try to create the rawtransaction:

createrawtransaction
'[
{"txid":"03a4ffcc792525b4ddaecc05054114f2ad8aff8b7563cd41cdb496e2177d0117","vout":0},
{"txid":"03a4ffcc792525b4ddaecc05054114f2ad8aff8b7563cd41cdb496e2177d0116","vout":0}
]' 
'{"mwCwTceJvYV27KXBc3NJZys6CjsgsoeHmf":0.05}'


The result of this call I use for signing:

signrawtransaction 
020000000117017d17e296b4cd41cd63758bff8aadf214410505ccaeddb4252579ccffa4030000000000ffffffff0100b4c404000000001976a914ac19d3fd17710e6b9a331022fe92c693fdf6659588ac00000000 
'[
    {"txid":"03a4ffcc792525b4ddaecc05054114f2ad8aff8b7563cd41cdb496e2177d0117","vout":0,"scriptPubKey":"a91421ce1507d06ed2742be0bf18a018bbcdd812a26487","redeemScript":"00149835f2e0dff9d7f6a4060140696bc7e00b12edd5"},
    {"txid":"13a4ffcc792525b4ddaecc05054114f2ad8aff8b7563cd41cdb496e2177d0116","vout":0,"scriptPubKey":"b91421ce1507d06ed2742be0bf18a018bbcdd812a26486","redeemScript":"10149835f2e0dff9d7f6a4060140696bc7e00b12edd6"}
]' 
'["cMahea7zqjxryy6NWaKxmhDyb1JzuNKCZAg8sxaJoXSBkRXjnib9"]'


At this point I get the error Missing amount and I can´t figure out why.
I´m not sure which values to use for the signrawtransaction() call. Should I use the same txid and vout values as for the createrawtransaction? Where do I get the correct scriptPubKey and redeemScript values from?

Note: the provided txid´s and addresses are only samples (maybe not valid) and not the ones I´m using for my code.

UPDATE:

Latest unsigned raw transaction in BTC live net:

if you are on testnet/regtest, it is completely ok, to provide "correct" data (no need for masquerading). There is the famous 2-of-3 multisig from Gavin, which provides a step by step approach using RPC. This should give you the idea behind. 

Generally you are correct, you would search for listunspents, take one of the transaction numbers, and see in the transaction, which unspent output you can use (usually it is a 0 or 1 for the first or second). And for sure this transaction should have some amount, that you can spend. Use "decoderawtransaction" to see the details of the tx. When you have created the tx with "createrawtransaction", then it returns a string of data, that can be used as parameter to the "sign" call.
