Snippet in Chunk

I’m using TVExplorer for a product search on my website. I’m trying to add spaces between the items of a delimited list in the search results. I can place the [+stats+] placeholder in my searchresults chunk and the information appears, but with no spaces (item1,item2,item3).

I have a basic snippet that will add spaces between these items but I can’t get it to work by adding it to the chunk. I’ve tried adding the following but nothing appears; what am I doing wrong?

Maybe try :
