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

@russian-dima
I need when quantity >0.
continue displaying the box(boxQty) with the (-) button!

On my WEBSITE LINK you can see it working with the console by push() correctly on the variable.

The only detail now is to leave the boxQty open when the quantity is greater than 0.

Just to reinforce. I left the file with the code on the page.

Thank you very much!! Help me!!
