# [Plugin: upPrev] ReferenceError: Can't find variable

 * I have included the upPrev js into my combined js file and it works perfectly—
   UNLESS I visit the homepage or any other page which is not specifically a _post_
   or _page_. Here’s the error I see in the console:
 * `ReferenceError: Can't find variable: iworks_upprev`
 * JS is not my forte beyond a certain point so I’m at a loss as to how to supress
   this error message. Here are a few links where the error can be seen:

 * Replace
 *     ```
       upprev/scripts/upprev.js
       ```
   
 * with trunk version
