    Hi,

    I'm having a very steep learning curve right now but have got my head around hidden variables to make a 2 page form. However I'm stuck on the next bit.

    I can pass variables from page 1 to page 2 ok, but I need one of the values to trigger particular form fields.

    On page 1 I have a question - if the answer is 'yes' I just go to the basic form on page 2. If the answer is 'no' I need to add a couple of extra fields to the form on page 2.

    I think I need some sort of conditional statements here but am not sure right now how to implement this.

    Is there an easy solution to this?

    Thanks

    <?php if (!empty($_POST['trigger']) && $_POST['trigger'] == "no") { ?>

<input type="text" name="trigger-explanation">

<?php } ?>

    I think there's no need for an explanation, right ?
