report that wont show data when different table added

I have modified the Order Entry database that comes with Access so that there
are more than one catagory of product in the sub form 'order details'. I did
this by creating a new table that is identical, apart from the table name and
field names, to the products table. i have got this to work fine and all the
data seems to work, until that is i try to run the invoice report. this is
fine until i add the new table to the query in order to add the fields to the
report to give me a complete invoice. the report displays a message 'no data'
closing report. if i turn off the no data 'event' i get report which give no
data regarding the order. if i run the query it is fine until i add the new
table. if i create a fresh query with the products table and the new table it
works fine, if i add the order details table it won't run. in fact it works
fine with any two of the three tables. any one know anything.
