Hi guys, I have a form that has two buttons on it, one yes, one no, and at the moment I capture the clicked button into a database, but for some reason, it doesn't always capture the clicked button, I have gone through all my code and everything seems fine, here is the form

            <div id="mid_prompt">
            <form  action="refer.php" method="post" onsubmit="return submit_form()" >
            <div class="prompt_container" style="float: left;">
                    <span class="prompt_item"><input type="image" src="images/yes.jpg" alt="submit" name="refer" value="yes" /></span>
            </div>
            </form>

            <form action="thank_you.php" method="post" onsubmit="return submit_form()" >
            <div class="prompt_container" style="float: right;">
                    <span class="prompt_item"><input type="image" src="images/no.jpg" alt="submit" name="refer" value="no" /></span>
            </div>
            </form>
        </div>

I am using sessions to carry the variables all the way to the end of the forms where I then write all the data to a database, I have checked my sessions and they seem to be working fine, the only one that is giving problems is the yes/no.

So basically I need it to capture that yes/no everytime.

Thanx in advance!
