Problem: I have two Forms. When one Form is submitted, I would like to redirect the User to the second Form, but I would like to add a URL parameter based on the selections in Form 1. That URL parameter should be used to preselect one of the fields in Form 2.

Solution: The cred_field shortcode accepts an attribute called "urlparam" that you can use to pre-define field values. For example:

[cred_field field="mobile" post="agent" urlparam="mobilenum"]

Then in the URL:
http://yoursite.com/form-page?mobilenum=123-456-7890

To set a URL parameter value in the redirect URL based on a custom field selection, use the cred_success_redirect API:

add_filter('cred_success_redirect', 'custom_purchase_redirect',10,3);
function custom_purchase_redirect($url, $post_id, $form_data)
{
  if ($form_data['id']==12345) {
    $email = get_post_meta( $post_id, 'wpcf-e-mail', true );
    $phone = get_post_meta( $post_id, 'wpcf-telefonni-cislo', true);
    $redirect = $url . "?fapi-form-email=" . $email . "&fapi-form-phone=" . $phone;
    return $redirect;
  }
  return $url;
}

Problem:
How to calculate total of CRED form field values and display total in email notification

Solution:
To calculate the Total, you need to add the custom shortcode to your current theme's functions.php file and pass the values as argument and shortcode should return the total.
You should add the custom shortcode to CRED form's email body as required.
