You have a financial statement workbook with 2 sheets, one that should be expanded and one that shouldn't?

You need to have 2 "items" in your Statement Group. They should both specify the same statement filename. In the first one, put a checkmark on the sheet(s) that you want to expand (in the "Tabs" selection box on the right) and put a checkmark on the "Expand Smartsheet" option. in the next item select the sheet(s) you don't want to expand and make certain there is no checkmark on "Expand Smartsheets".
