gform_confirmation checkbox

I'm trying to display a conditional confirmation message based on a checkbox being ticked or not in my form. I've searched the forums for this answer and cannot seem to find it.

Here is the code:

function custom_confirmation($confirmation, $form, $lead, $ajax){
	if (isset($lead[3]) && $lead[3] == 1) {
                 $confirmation = array("redirect" =>"http://www.drumblebee.com/login?error=youhaveanerror");}
        else {$confirmation = array("redirect" =>"http://www.drumblebee.com/login/");}
return $confirmation;
}

The problem is despite me checking (or unchecking) the box, the $lead does not seem to recognize the form value.

The form code is:

<input name='input_3.1' type='checkbox'  value='1'  id='choice_3_1' tabindex='3'  />

Any help would be appreciated. I'm sure it's something very small I'm missing.

Thanks,
Tony

add_action("gform_confirmation_3", "custom_confirmation", 10, 4);

The thing is, I can get the other values from the form within the custom_confirmation function.

$lead[1] and $lead[2] store the correct values.

And if I go into the admin I can see that the checkbox value is stored:

Thanks again!

How would I do that? It displays the confirmation page after I hit submit on the form.

I created an extremely basic log table because I couldn't get print_r to work correctly. This is the serialized array when the checkbox is checked. You can see there is a value there.

a:21:{s:2:"id";s:3:"117";s:7:"form_id";s:1:"3";s:12:"date_created";s:19:"2012-12-20 21:35:19";s:10:"is_starred";i:0;s:7:"is_read";i:0;s:2:"ip";s:13:"50.200.57.190";s:10:"source_url";s:32:"http://www.drumblebee.com/login/";s:7:"post_id";N;s:8:"currency";s:3:"USD";s:14:"payment_status";N;s:12:"payment_date";N;s:14:"transaction_id";N;s:14:"payment_amount";N;s:12:"is_fulfilled";N;s:10:"created_by";N;s:16:"transaction_type";N;s:10:"user_agent";s:108:"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.97 Safari/537.11";s:6:"status";s:6:"active";i:1;s:5:"admin";i:2;s:13:"sdkjbwiojubss dsd";s:3:"3.1";s:1:"1";}

Nevermind - got it.

Hopefully this will help someone else - you have to put the value inside the $lead array in quotes:

so $remember = $lead['3.1'];

worked.
