@RISK Error: #VALUE Errors When Opening Workbook
Cause: This can be an artifact of Excel timing with some workbooks. Solutions: Press Ctrl+Alt+F9 to force Excel to recalculate the formulas. If this doesn't help, you can force Excel to rescan the workbook for dependencies by pressing Ctrl+Alt+Shift+F9. If 1 and 2 both fail, you may have Trust Center settings that are preventing @RISK from running. See Excel Macro Security Settings for guidance.
