I installed the package from this link and its working fine. Then I create the one multisig contract. when creating the contract I got one new address.
I can deposit that address but for withdraw process it shows the error message like you need to unlock the account on send transaction process on Web3 API.
I am also trying the unlock function but here we need to provide the password but for this contract address we didn't know the password.
So please help anyone to unlock the contract account. I should use that address for withdraw process because by that process only the multisig process working.
