How to make changing text on GUI with multiple "Format Number As" procedure blocks

I am Making a mod that gives the player stats. For this mod i am using a Player Persistent Number variable for both the players level and EXP. I want to make a procedure that will "Return Text" so that in the GUI the text will display "(Current EXP) / (A number that i define relative to the "Level" variable)". i can make a procedure that can print the first line (The "Current EXP") but i dont know how to add additional lines to the text that the procedure will return. Below are some links to some screenshots of what i have so far.
