I am trying to fill out the LEED user EBOM SSc4 Alternative Tran Results Calculator and I keep getting the same error message. No matter what data I enter into Step: 1, I receive the following message "The number of FTE occupants who received the survey is greater than the total number of FTE occupants in the building." I am using Excel 2010 and have received the message in and out of compatibility mode. Anyone else having this error or have any advice?

Thanks.
