i have a small problem, i'm using a PHP form to get answers off a contact form I created. 

Here is the php:

```
$email_message .= "E-Commerce: \n";
$email_message .= (isset($_POST['no-credit'])) ? 
                      "No credit card: $".implode(" ", $_POST['no-credit'])."\n" : '';
$email_message .= (isset($_POST['paypal'])) ? 
                      "Paypal: $".implode(" ", $_POST['paypal'])."\n" : ''; 

```

When i get the email, and "paypal" or "no credit" is not checked "E-commerce:" still shows up. I tried something like:

```
$email_message .= (isset($_POST['no-credit'])) ? (isset($_POST['paypal'])) ?
                      "E-Commerce: \n";
$email_message .= (isset($_POST['no-credit'])) ? 
                      "No credit card: $".implode(" ", $_POST['no-credit'])."\n" : '';
$email_message .= (isset($_POST['paypal'])) ? 
                      "Paypal: $".implode(" ", $_POST['paypal'])."\n" : ''; 

```

But it did not work, i fell like i'm not far away but i can not get my hands on it.

Thanks
