What I am looking for is this:
Assuming I have a column defenition like this and I do grouping by drag and drop:
title: "Product Title",
"#= title #:#= value # Count(#= count #)"
How do I get the header to look like like "Product Title: This is a product title Count(5)"? I keep getting title undefined. I am able to access the field but not title for that field.
