here is where i ran into the same problem when coding this. i couldn't find out how to insert a breakline. everytime i put in /r/n it would actually put those characters into it. this was for inserting the description then 2 lines down putting the link. i had to come up with a work around for that.
Code:
Open up your replacement variable manager (in admincp -> styles & templates -> replacement variable manager) and add the following entry:
Style: [select whichever style you are using]
Search for text: {br}
Replace with text: <br />
