ISNUMBER Formula Help
I have a sheet that has an INDEX look ups from another sheet for one of the look up Row (Target Install Start Date) will either have a Date or Text. In a new row I want to either use the date in a formal or just the text. I've done this in excel with =IF(ISNUMBER(G2),(G2+H2)-1,G2) but when I try to do this in Smartsheet always return the False statement and does not do the formula if true. Here is a screen shoot -

So the ISNUMBER function isn't going to work the same way in Smartsheet as it does in Excel. A date isn't read as a number in Smartsheet, where in Excel it is read as a number. You will need to build your formula to account for that difference in logic.

Thank you that insight. I reversed the logic and used ISTEXT. It now works as expected.

Use ISDATE instead of ISNUMBER
=IF(ISDATE([Target Install Start Date]@row), [Target Install Start Date]@row + [Estimated Install Days]@row - 1, [Target Install Start Date]@row)
