    I have a client who wants to have 10 questions all with 3 radio buttons (A, B and C). At the end of the questionnaire an HTML box will display if most of the answers are A, a different one if most of the answers are B, and a different one if most of the answers are C. Is this possible with Gravity Forms? And does my explanation make sense? Thanks! :)

    It does make sense. You want to change the confirmation message conditionally based on the answers which are submitted. You will have to total all the C submissions, all the B submissions and all the A submissions and then change the confirmation message dynamically. You can use PHP to count up the number of A, B and C choices, then you can use the gform_confirmation filter to change the confirmation based on which choice was made most often.

    Thank you for your answer, that is exactly what I want to do! The gform_confirmation page looks easy enough to figure out. Could you point towards a tutorial or a page on how I would add up the selected radio buttons, or how I could hook into this from the functions file? I just bought the plugin today so I am still learning. Thank you!!!!

    Please take a look at this code. http://pastebin.com/B1sjjwwQ

    One problem will be if out of 10 questions someone answers where there is no clear "mostly" (i.e. 5 and 5, or 4, 4 and 2.) That is not accounted for in the code, but the approach should be sound.

    Thank you!! One quick question, since the answers are going to look like this:

    A. Something here
    B. Something else
    C. Something another

    How, with that code, would I strip all characters except the first? I'm assuming that would be the best solution...

    Thanks!

    nvm I figured it out by using:

    for($i = 1; $i <= 10; $i++)
                $questions[] = substr($lead[$i], 0, 1);

    Thank you so much for your help!!
