Commented Unassigned: Alert not defined. [671]

Hi,

I'm attempting to use Alert.Js on the form. I've added the reference in the form properties but the Alert object is undefined.
Am I missing a step?

Thank you in advance.

Apologies, this should probably be in discussion... I should also add that I'm trying to call the alert from a html web resource.
