Adding funds to my wallet

When adding funds to my Nifty Gateway wallet, MetaMask always says insufficient funds. If I up the amount from Nifty, the total goes up again and tells me I still have insufficient funds. I am a noobie at this, so its obvious to me I am doing something wrong, or don’t understand this process yet. My goal is to start offering original art to auction on NG.
