Add line breaks to this formula

Add line breaks to this formula

Hey Everyone,

I'm having a hard time trying to figure out how to add line breaks to this formula.

input.Notes = "Sets = " + SingleWorkout.Sets + "<br>" + "Reps = " + SingleWorkout.Reps + "<br>" + "Instructions = " + SingleWorkout.Instructions;

It should look like this...

Sets = XXX
Reps = XXX
Instructions = XXX

but instead it just inputs the values as one line and the <br> as text.  

Any help would be great.  Thanks!
