SQL Help - Is it possible to do the following?

Hi all,

I have created a SQL query that gives me the following, but I want to build
onto it:

Project Manager/Job Name/Contract Revenue/Labour $/Material $

What I am trying to now do is:

1) Create a field in the query Margin = Contract Revenue - Material $

Any ideas?

Thanks

James
