Problem with select/option not showing text

[Simon_4]

Hi

I just have the follow problem. In my form, I have a select option. Usually I should see some text there, I can change and open the dropdown menu, but I not see any text. What it could be?

Here is the url: http://web159.login-142.hoststar.ch/memberd/de/prices/

And here some html code:

<form action="/memberd/enquiry.php"  method="post" id="genForm">
                    <h3 class="colour-holiday">Bitte geben Sie Ihre Daten ein</h3>

                        </form>

and here my css:

    margin-top: 15px;
}

.contact-form .name, .contact-form .email, .contact-form .address, .contact-form .city, .contact-form .country, .contact-form .postcode, .contact-form .contactno, .contact-form .hotel{

    border-color: #aaa;
}

If I remove the height: 12px; from .selservice it shows again. That's because with the padding of 10px, a height of 12px only shows the whitespace of the padding.
