[SOLVED]How to perform a function on just one repeater item?

Thanks @russian-dima ,

I have been reading the documents and the link since this morning.

However, running the line of code you sent me. it worked perfectly in “Wix Viewer”. When I publish the site, it doesn’t work in the browser.

Just like the first problem I had ;(

Thank you very much and if you find something and can help me. Strong hug
