I have been unable to input data into the provided survey results calculator. After putting in my values for "regular building occupants", I choose approach 1 and try to input the same total number of regular building occupants for "regular building occupants who recieved the survey" but get an error that says, "the number of FTE occupants who recieved the survey is greater than the total number of FTE occupants in the building". Similar errors continue to happen if I skip this section and got to the rest of the form. Am I doing this wrong? Could the format of the excel file have changed when I saved it to my version (2010)? Does anyone have a suggestion on how to use this spreadsheet correctly? Thanks!
