Variables.ClearList List: NewVar ClearedList=> NewVar

 Display.ShowMessageDialog.ShowMessage Title: $'''its empty''' Icon: Display.Icon.None Buttons: Display.Buttons.OK DefaultButton: Display.DefaultButton.Button1 IsTopMost: False ButtonPressed=> ButtonPressed

@dominono9 , in the Display Message box when you select the List variable it will give you the .Count property. You can make use of that. It will return 0 if the List has no values.

I am not sure what you mean by "the empty function" but this definitely works:

SET NewVar TO ['a', 'b']
Variables.ClearList List: NewVar
IF IsEmpty(NewVar) THEN
Display.ShowMessageDialog.ShowMessage Title: $'''its empty''' Icon: Display.Icon.None Buttons: Display.Buttons.OK DefaultButton: Display.DefaultButton.Button1 IsTopMost: False ButtonPressed=> ButtonPressed
END
