Hi there
I have a drop-down from an enumlist, base type Ref
I need to require the user to choose at least two from the dropdown.
COUNT([_THIS]) >= 2 is telling me I’m not using Count properly
COUNT(LIST([_THIS])) >= 2 gives an invalid message no matter how many (more than zero) are selected
COUNT([YourEnumListColumn])>1 should be fine
Hey man,
you can use _THIS: 
ISNOTBLANK(INDEX([_THIS], 2))
This should be a bit more performant than counting and comparing.
Also make sure Require? is Checked.
Set Invalid error message to “Select at least one more” or something like that.
Cheers
