Thanks
Genghis, I was on the verge of doing the same when I thought that there must be an easier solution amongst all the 'functions'
Ex Grunt
You got it in one.
Require the result as a simple list (on my FY annual summary page) with a running total ie
Charter £total amount of revenue allocated code 1
Business 1 £blah amount of revenue allocated code 2
Business 2 £blah etc
Then I can provide adequate briefs/pie-charts etc
Thank you in advance
