"Submit a Form" Required field does not stop Submit
A form able to work in Windows or Android etc. is required.
It has to have a 'Submit' button and some 'Required' fields.
Apparently the only 'submit' action that is supported by Reader for mobile is 'mailto:<target email address>' placed in the URL of the 'Submit a Form' action builder. This 'Submit' setup works on both Windows and Android.
The problem is that this does not check the Required fields. Any empty ones do not stop a 'Submit' action.
Can this problem be overcome, and if so how?
