Francisco Monaco on "[Plugin: Contact Form 7] Adding [_post_title] to a textarea value"

Hi, I'm working on a real state website and we need the value of the textarea to display the post's title. It should look something like this:

"I want more information on Sunny Isles Chateau Beach"

I tried:

"I want more information on [_post_title]"

But didn't work as expected.

I would very much appreciate any help on this, so, thanks in advance!
