I'm after some help with just one line of this code please. (line 10 ?)
Basically what it does is list links (with titles) to all posts created by the "author" of the post in question.
What I'd like to do is change it from the post author to a Custom Field I've created called "business" and group all posts that have the same/common value for the custom field "business"
I'm pretty sure it's just line 10 that needs to be changed
Thanks in advance, much appreciated as I've searched everywhere for this.
