In the Steem account name, you have to make sure you type the username with no @ and no caps, for example in your case it would be apolymask then you just copy/paste the generated address from blocktrade in Coinbase's send option.

Thanks for trying, but he didn't even type in his account name it was automatically in there by default so it should be right..
