The code expect an editable poly object or an object with applied Edit Poly modifier to be selected. If nothing is selected you will see the above error.

This will show you a message when no object is selected.

(
	if selection.count == 1 then
	(
		selObj = selection[1]
		if classOf selObj == Editable_Poly then
		(
			selObj.paintDeformAxis =3
			selObj.paintDeformValue = 2
			selObj.paintDeformStrength = 0.2
		)
		else
		(
			if classOf (epMod = selObj.modifiers[1]) == Edit_Poly do
			(
				max modify mode
				epMod.paintDeformAxis = 3
				epMod.paintDeformValue = 2
	-- in max2020 the Modify Panel must be open so the next  setting to be set
				epMod.paintDeformStrength = 0.2
			)
		)
	)
	else
		messagebox "Select an object" title:""
)
