Show post title Post in next form to Page

Hello,

i had create contact form list:
in contact form create 2 form: booking1 & booking2
in page i had add page Booking with: [contact-form-7 title=”booking2″]
and in post add do_shortcode( '[contact-form-7 title="booking1"]' );

How to echo title post in page Booking when next contact form Post to page Booking.

i had add code [form your-email] is ok(echo email submit)
but add code [form _post_title] or [form wcf7.post_title]... is not echo title post.

Thanks so much.
