Can't drag report formula into report preview pane
I am creating a summary format report. When I drag "Add Formula" over to create a new column, the entire grid highlights and I get the formula builder screen. I create my formula and it passes syntax check. When I exit the formula builder screen, I have a new row under "Formula" with the name of my formula, but I can't drag it onto the screen to become a column. If I try running the report, the formula doesn't show up.
