Trying to swap GTO DATA and Others

For the life of me I can not figure out how to use the Bancor Swap in conjunction with MetaMask to swap a bunch of coins. Where/How do I send the coins to be swapped??

Please help…

Hi Paul. What do you mean with: ‘in conjunction with MetaMask’? Do you mean you know how swapping tokens/coins works on Metamask, but you can’t figure out how ‘the same thing’ works on Bancor?
