Ukrycie za pomocą hidden lub innym kodem

[brt00]

W pliku szablonu product.tpl, chciałbym wprowadzić jedną zmianę. To znaczy, chciałem dodać kod, dzięki któremu, jeśli cena = 0, to nie wyświetli się cena i przycisk dodaj do koszyka, będzie po prostu jakoś schowany.
Poniżej załączam wycinek pliku tpl odpowiedzialny za wyswietlanie ceny i proszę o pomoc. Co i jak dodać, w razie czego cały plik wyślę jakoś na pw, bo tu nie moge wkleic (jest za długi)

spróbuj z tym kodem powyżej, nie sprawdzałem czy działa - ale powinien
