The question I am trying to ask a seller is the first time I have contacted him.  I did try to pass an email address to a different seller last week so I assume thats where the problem has come from, Thank you John


Yep, trying to exchange an email or any contact detail before a purchase , eBay may well have placed sanctions on your ability to send messages.  May also depend on what you are actually asking.
