Editing File Show and View- Product in File Show

HI

This is what I see in my url : eazfix.com.au/index.php?option=com_hikas...yout=show&Itemid=128

I guess from the url, I would be editing under Configuration -> Display, View is product and File is show:

I go in and find the line:

<div id="hikashop_product_price_<?php echo $variant_name;?>" style="display:none;"> and change to

<div id="hikashop_product_price_<?php echo $variant_name;?>" style="display:none;color:blue;">


But nothing happens.

Could you tell me if I am missing something?

thanks

Patrick
