I'm referring to an earlier post (http://community.qlik.com/message/101254#101254) but I have run into a couple of problems with it and wondering if anyone could help. I'm trying to incorporate John's solution into my application but I'm having trouble combining it with set analysis expressions: =$(money(Sum($<Field 1 = {'abc'}>}Field 3))) works fine but=$(money(Sum($<Field 1 = {'abc'}, Field 2 = {'xyz'}>}Field 3))) evaluates to null John's original solution is attached. Any thoughts on this would be much appreciated. Thanks, Andy
