I have a Validation Setting column which seems not to be working with the formula =RTW>=StartDate and I get error:

'Something went Wrong'

However it works if I have the formula =RTW=>Today() it does work, How can I get the validation be ColumA=>ColumnB?

You cannot add reference to other columns under Column Validation settings.

You have to add this formula under List Validation settings.

Follow below steps:

  1. Go to SharePoint list
  2. Click on Settings icon and select List settings
  3. Select Validation settings
  4. Add formula & user message and click Save

Use below formula in list validation settings:

=AND([EndDate] >= [StartDate], [RTW] >= [StartDate])
  • I already have =[EndDate]>=[StartDate] in this validation, can I combine both? if so which formula is correct as always get confused with the IF/AND/OR logic. Also why would the validation within the column not work? what kind of validation can be used in the column? Commented Apr 9, 2021 at 6:47
  • In Column validations, you cannot add reference to other columns. For updated formula, check my updated answer. Commented Apr 9, 2021 at 9:06
