Is it possible to add or subtract data from to separate sub reports?  Here is my set up:

Main report shows:

Column 1 = Technician names
Column 2 = Sub Report 1 (shows total number of orders tech has, linked by Employee ID to the main report.)
Column 3 = Sub Report 2 (shows total number of units the tech has on hand, linked by Employee ID.)

Main report parameters are showing all technicians that the "fire date" is null, Employee Type is equal to "T" for technician.

Now the reason I have to do sub reports is because I can't get the totals without using them because when I do the report just blows up and I get crazy data!

So what I'm trying to do is have the report subtract the number shown from Sub Report 1 (which is a summary count of work orders) from Sub Report 2 (which is a summary count of units)? 

Is this possible or am I pulling out my hair for no reason?

Thank you so much!  This was a tremendous help!  I ran into a few other problems but that is more with my companies data bases that are a complete mess! 

Either way you've pointed me in the right direction and from there I was able to get it done!  Thank you again!
