In the line, “$0.0.tag” the first property $0 refers to the tuple itself that is created from the zip function, the next value, 0, refers to the “piker”, which then has the tag property.
I hope this makes sense. Try it out and see how it works
The whole concept of doing what you’re asking for is bad coding practice, im convinced you can solve your problem in a much more efficient way. This is a typical use for a simple array, where the index will correspond for the picker number you want to address. Have you tried that approach?
