HELP - Issue with dropdown filter and duplicating

Hi all,

I am needing help to solve this problem!

I am trying to create a comparison dropdown menu to compare two products side by side.

I have created the CMS dropdown function but when I go to duplicate it, the link breaks.

  1. I have tried updating the code
  2. Creating it as a symbol and then duplicating
  3. Creating two separate CMS lists (Same info or both)

I am an absolute beginner when it comes to front end code also so this may be the issue.

I have been following the f’nsweet website to work out the code needed for this function, which works until I need to duplicate it.

This is the page.

I appreciate all the help I can get! :grin:

Thank you!
