I have two spreadsheets. One spreadsheet has a vast amount of flow data recorded at 15 minute intervals on specific days, while the other spreadsheet I have a column for the MIN, AVG, and MAX calculated flow rate for each day. For some reason when I run DMIN and DMAX the data keeps showing up as 0.0000 for both even though this clearly isn't right seeing that I have no such values. Some of the values are very close to zero but when I try to adjust the decimal place it still shows a 0 value. What could cause this to happen?

Thanks
