Hi, I would like to use code snippet for clearing Marketo tracking cookie from forms submission( form.addHiddenFields({"_mkt_trk":""});). I am wondering is it possible to use it as if condition, for example, if you don't checkbox in form than disable tracking. And all this is related to landing pages, I want to do this on a landing page in Marketo, not in an embed code which you usually copy from Form Actions.
