Append Query Problems

Hi

I am doing an A level database project. I need to build a system to deal with ordering and selling products.

I am trying to make an append query that will append all the products bought in my "invoices" table to my "archive" table. I want invoices that are three months old to be transferred the the "archive" table. I have been trying to put a criteria in the query for the Date field but I haven't managed to find an expression that works.

I'm sorry if this is too simple and you guys think im just being stupid.
I figured it was worth asking on here!! It's really bugging me.Show us what you got so far. Also ... look up dateadd and datediff in BOL.|||Sorry, what is BOL?
"Date"<=#01/01/2006#

Is that what you mean by show? I don't know how to show the whole query :-s|||Can you write a SELECT statement to retrieve the rows that you want to archive?

-PatP|||Thanks but I don't know what a select statement is! Is it the same as a select query? there's something about that in one of my books.|||Is this project in Access? You may need to ask over in the Access forum...|||Yes it is. I realised after I posted here that there is an access forum too. I have posted in there now thanks!
