you wouldnt know how to get a subtotal for Expr1 (i.e. the above calc) in this area would you? Sorry, we havent got great report writing skills. Need to go on a course!

You would find it useful to get some training on this but put simply you can copy/paste the field you want to subtotal, put it in the required section, then in the Properties of the new field set the Function to Sum. 

Also important in having it subtotal correctly are the Evaluate Section and Reset Section settings; the correct settings for these will depend on how your report is designed, so best to have a play.
