Time entry Smartsheet vs. Excel
Hi All,
Problem  I have a VERY simple Excel spreadsheet for collecting hours and it has been working fine, but now I want to use some functionality I know that will be easier to complete if I move the sheet to SS. I exported the sheet to SS and my very simple formula no longer works.
Goal  Have SS return the the difference (hours worked) between Start and End columns.
Details  The formula in Excel was =sum(EndStart), which I changed to =SUM([End Time]@row  [Start Time]@row). The results using the SS formula is the #Invalid Operation error.
Any thoughts? All help is greatly appreciated!

It looks like there is an issue with the formula syntax when you moved your spreadsheet from Excel. The formula
=SUM([End Time]@row  [Start Time]@row)
is incorrect for calculating time differences in Smartsheet.In Smartsheet, to calculate the difference between two times and get the result in hours, you should use the
HOUR
andMINUTE
functions combined with some arithmetic to correctly handle the time difference. Here is the adjusted formula you can use:=IFERROR((HOUR([End Time]@row) + MINUTE([End Time]@row) / 60)  (HOUR([Start Time]@row) + MINUTE([Start Time]@row) / 60), "WHATEVER EVER MESSAGE YOU WANT TO SEE")
This formula calculates the hour and minute parts of both the start and end times, converts the minutes to a fractional hour, and then subtracts the start time from the end time. The
IFERROR
function is used to handle any potential errors gracefully. You may need to adjust to accommodate your specific column headers
