paypal. accept a payment?

hi, anybody know how to accept a pyment?
a person has sent a payment and gets a message saying the recipient (me) has to accept it to complete the transaction. i do not know how to accept it and have never been asked to before. any help appreciated.

If they have sent it to the right person, you should also get an email from paypal saying that you have received a payment with a link to accept it.
Or just log into your paypal account and click the link next to the payment to accept it.

no email/link and nothing on my account, something gone wrong. cheers potdog.
