I am running joomla and installed the facebook like box, and am trying to use if for the first time. I understand the directs and have looked up the facebook id for the page I am linking it to. The issue i am having is that when I hit save the proper id that i have entered is replaced by an invalid ID. I could really use some help on this one, I have honestly no idea what to do about this.

Facebook Page ID field is for backward compatibility for earlier version of Facebook Like Box.
The easiest is to just copy your current Facebook Page URL from browser and fill in to: "Your Facebook Page URL" field.
