CMS Combine not working (can someone please help?)

Hey, everyone. I hope you’re all doing well.

I’m trying to combine two CMS collectionsions using Finsweet CMS Combine, but I can’t get it to work. The collections are in the first section after the hero on the home page. I only want 3 items to show, but want them to be a mix from the 2 collections.

I pasted the custom code where they said to and I added the attributes, but I’m doing something wrong and could really use some help.

Thank you so much!
