$item_id_sanitize is not declared in giftitems.php

Hi, I’ve been having some problems which have been started with the new versions, so I digged a bit deeper in the code.

What I’ve seen on line 245 of the giftitems.php is $item_id_sanitize has been used but has never been declared. There are 3 more occasions on lines 249, 286 and 288.

This is causing some null value problems on our end and everytime we upgrade to the new version we need to go inside the code and manually change all the $item_id_sanitize variables to $item_id which then fixes our problems.

Are you aware of this or is this an issue on our end with some missing includes?

We have the latest version of the plugin at the moment.

Thanks.
