the reality is: what you re trying to accomplish is not supported by Contact form solution pack.
it takes a good understanding of the PHP code on the page to be successful.
the big issue i see on the page right now, is that you have not implemented the suggestion I made initially.
there are 2 groups of the validation / email server behaviors on the page. the first validation server behavior is at lines 11 - 30. the trigger code is still set to use the any form post trigger:
if ($_SERVER["REQUEST_METHOD"] == "POST") {
instead of the button submit trigger:
if ((isset($_POST["Submit"]))) {
the first universal email behavior is at lines 31 - 42. It is also still using the current page submit trigger instead of the button pressed trigger.
line 43 - 60 is the second server validation behavior still using the current page submit trigger code
the only block using the trigger code change i suggested is line 61 - 72.
you need to change the trigger code for each of those server behaviors to occur on the appropriate button press.
another issue is that you will not be able to use captcha security on both forms, it can only be used on one of them.
