Hi all,

Despite following the instructions tab details, I have been encountering Low-emitting spreadsheet/calculator errors when attempting to generate assembly calculations to overcome several (general emissions) non-compliant/non-tested wall products. The line items just won't appear in Option 2 summary tab....Before I reach out to GBCI directly, I wanted to check the forum....

In short, has anyone else had success or issues with the USGBC issued calculator? I'd welcome any tips in navigating its data entry quirks.
