HELP!

I F*** up..
I was just looking at the php in gift-cards-for-woocommerce/includes/scripts.php
and when I left the page, a “page does not exist” happened. And this comes up when I try to enter the shop….

Parse error: syntax error, unexpected ”Giftcard does not exist!” (T_CONSTANT_ENCAPSED_STRING) in /customers/1/d/4/spekebua.no/httpd.www/wp-content/plugins/gift-cards-for-woocommerce/includes/giftcard-checkout.php on line 182
