In order to trade (buy and/or sell) on the Market you need to have your Paypal account connected to your marketplace profile.
To achieve this please take the following steps:
1. You need to have a verified Paypal account. See the instructions on Paypal how to get verified:
2. When you're verified you have to use same credentials in your Marketplace profile as in Paypal.
So firstname, lastname and email address should have an exact match (case sensitive)
