Validation user message not showing

Question

I have a formula in List settings-> validation settings.

The formula validates correctly. The user message I entered does not display, it displays its own message below which is

Error: The validation formula has evaluated to an error.

How can I show my User message?

See a screenshot below:

Answer 1

I can reproduce this issue in my environment. I haven’t found other formulas that block the custom user message but at least DATEDIF function is doing that.

You can switch to another formula like

[Original planned end date]>=[Actual start date]

or

[Original planned end date]-[Actual start date]>=0

It functions the same in this scenario.
