Login button click not working

I’ve tried the steps mentioned in the documentation, yet button click is not working for me.
Here’s my HTML:

Log in

Here’s my code:
navigate https://myLoginUrl
setValue name=username myUsername
setValue name=password myPassword
submitForm className=marketing

navigate and setValue are working perfect.

Does the form have an action? That appears to be missing from the markup (i.e. where it submits the form data to).
