Text wise, I have shared what I think were the relevant changes in my previous comment.
UI wise, look through the Interface Script for a set of two UI_Infields and a UI_Outfield that should include the line UI_Outfield "Story Elevation Text", if your object is the same as the image posted by the now anonymous user minus the prefix, else some similar comment to do with text. Copy the lines down and increase the first numbers by an increment common to the previous sets. Insert your new variables into the two infields and your display text into the oufield. In the case of my script, the infield with a similar Y value to the outfield would be lvlRL creating a checkbox next to a text label. These second infield would be for your Values of RL, SFL and FFL. I did not have a parameter for this so you would need to set it up in the Parameter Script then add the relevant IF statements and variables to the 2D Script.
