[selling projects on the market]

Hello Community,

I would like to sell products on the market .I have bought a product and I have confirmed the terms for the market. However I get the message that I don´t fulfill all requirements to join the market. What went wrong? 

I hope you can help me.

Thanks,

eishockeyfan

additional information: My account is older than 5 days and it still doesn´t work, and i don´t want to resell things I have bought before. I want to sell own created stuff. :)
