How can I translate "this"?

[pobliska]

I have a stripe with products availability, above the stripe I placed text in german (Verfügbarkeit), now I will translate it in english, how can I make it?

 

This is my code from product.tpl

<p class="dostepnosc">{l s='Verfügbarkeit:'}</p>
            <div id="stanMag"></div>
            <!-- END OF COPY -->
            <!-- number of item in stock -->
        <div class="content_prices clearfix">
            <!-- quantity wanted -->
            <p id="quantity_wanted_p"{if (!$allow_oosp && $product->quantity <= 0) OR $virtual OR !$product->available_for_order OR $PS_CATALOG_MODE} style="display: none;"{/if}>
                <label>{l s='Quantity:'}</label>
                <input type="text" name="qty" id="quantity_wanted" class="text" value="{if isset($quantityBackup)}{$quantityBackup|intval}{else}{if $product->minimal_quantity > 1}{$product->minimal_quantity}{else}1{/if}{/if}" size="2" maxlength="3" {if $product->minimal_quantity > 1}onkeyup="checkMinimalQuantity({$product->minimal_quantity});"{/if} />

Hi,

 

Have you tried to translate the text in backend?

 

Best regards.

Thanks for your reply,

this code I added manually, so I think, that it will be unavailable to translate it from backend.
