Undefined variable error

[Kjolebutikken]

Hi,

 

I get this error in my error log:

 

 

PHP Notice: Undefined variable: SHOW_PRODUCT_LIST_CATALOG_IMAGE in /home/kjolegal/public_html/butikk/catalog_products_with_images_full.php on line 23, referer: http://kjolegalleriet.no/butikk/index.php

 

In line 23 in the file catalog/catalog_products_with_images_full.php I have:

 

// Show image in Full Catalog
$SHOW_PRODUCT_LIST_CATALOG_IMAGE==1;

 

What do I need to change to get rid of this message?

 

When I try to open this page I only get a 500 error page.

 

 

Thanks :-)
