I am using Nintex Forms for Office 365, and trying to debug Task form in IE Developer tools. When query for a control using its class, like, NWF$(".lblMylabel"), it shows error message as NWF$ is undefined. Even tried with $ also, it says null.
Solved! Go to Solution.
Remember the form works inside an iframe. So if you just hit F12 and type the NWF$ it will refer to the parent window, where there is no such object defined.
Move mouse cursor over a field in the form, and from there click "Inspect" for example. That will open developer console for the iframe, and the NWF$will work there.
