I figured it out! Sorry. I wasn't sure of the wallet type but now everything is working out. Again, thanks.
Cool! But in any case you wondering what multi-sig wallet is, it is a type of wallet which requires multiple authentication to send the transaction.
It will create an address such that bitcoin received on that address can only be spent if multiple private keys sign the transaction together. For example, 2-of-3 multi-sig means at least 2 of the three authorised private keys are needed to spend the output.
Since you are only individual, you must go for standard wallet which I assumed you went for.
