[Plugin: TDO Mini Forms] wrong type of post (page)

I’m having trouble getting the edit form to work. I have used the widgets to create a form and used the auto generated page option.

I cannot see the form on the page as it gives the error:
That post you are attempting to edit is invalid

The log file shows:
Bad post_id!
Post with id 10 is wrong type of post (page) for 3!
etc…

Maybe it always requires a default post id? How do I specify “<?php tdomf_the_form(1,326); ?>” in the shortcut?

The documentation for the edit form is very poor!

Thanks for any help
