Currently, have a calculated column that calculates the difference in days between 2 date columns.
=DATEDIF([Issue Date],[Due Date],"d")
When there is no value entered or an incorrect value entered, it displays as "#Name?"
Tried wrapping IFERROR around it but not sure on the syntax.
Current syntax:
=DATEDIF(ISERROR(([Issue Date],[Due Date],"d")),"",([Issue Date],[Due Date],"d"))
