Help, I broke product display page!

Reading the forums here I wanted to change the picture displayed on the product display page to show the full picture and not the thumbnail.

Per the directions I changed tmpl/show.php
change:
if(!$this->config->get('thumbnail')){
to
if(!$this->config->get('image')){

Now when I go to any product page, I get nothing at all but a blank page. I changed it back and still get a blank page...

store.tk7studios.com/bracelets

Any help would be appreciated!!! Everything has been going splendid until this, and I'm set to go live next week.

took a leap of faith and reinstalled the hika module over itself, problem solved, thank god!

I didn't think of it at first as it has never been a problem up to now, but for whatever reason my editing program (hap edit) altered the php file when it opened. It happened again to me opening another .php file. I was smart to make a backup first this time...
