Adding additional URL to script

So new here, just joined but read a few of the things on here,

I am fairly new to scripting, well actually pretty darn new lol.  But im learning as I go how to edit and manipulate it to do what I want.

So here's where I am stuck. 

#URL for self Service
$URLToSelfService = "http://" 
I need to add an additional one to point to a completely different site.  The one above is mentioned in the email that gets sent out, but I need it to have both links.
So my question is do I just add another of above or is what would I need to add, to have another link in the email that gets generated.
Thanks!
