Multiple Forms on One Page

We have multiple property listings on a page with a contact agent button which opens up a gravity form with the necessary dynamic fields filled in to contact the respective agent. Each form is filled correctly and submits fine but once you have submitted one contact form all the other contact forms pop up with the thank you for submitting. Is there a way to override this setting so a user can submitted other contact forms on the page.

@iaan – I am doing something similar. I have a list of projects on a page with a form embedded into the loop that is retrieving the projects. This form allows a user to contact the author of each project.

So for each project that is displayed, there is a form attached to it that will send to the authors email address.
The form is the same on each project, shares the same ID and therefore displays the same message once the form is submitted to one of the authors.

The forms work perfectly and submit to only the correct author, it doesn’t submit twice or to any other author, it is just the message that is the problem.

Would there be any type of workaround to get the message to display on only the submitted form?
