I have entered the code as outlined to split products into columns

I have entered the code as outlined, however, it is not changing my form. Please see form at https://form.jotform.com/Lrichmond/clone-of-room-rental-fee---occc and let me know what I have done wrong.

I checked your form and I can see that the product list is now divided into 2 columns. I assume you're all set now.
