I could find the answer. This is all I did.
It looks like both the user and order have columns named id. And your criteria uses them both in the WHERE clause, which is giving the "ambiguous" mySql error message.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
