error in PRODUCT DETAILS

Entering "product details", I get the following error:
Fatal error: Call to undefined method shopFunctionsF::PdfIcon() in /homepages/33/d400318538/htdocs/templates/hot_cosmetics/html/com_virtuemart/productdetails/default.php on line 151

You can check it on my page:
www.pelucashop.com/index.php/virtuemart/tipo-de-pelo/natural

You know how I can correct it? thanks

open that file , you will see:

echo shopFunctionsF::PdfIcon($pdflink );

comment that line like this:

//echo shopFunctionsF::PdfIcon($pdflink );

then if you need pdf icon you can add below it something like this:

<a href="<?php echo $pdflink; ?>" class="MyPDFIcon" >PDF</a>


then add
.MyPDFIcon{
...
}

in template_css.css , and enter your style properties.

Thank you, solved!
