I need help making a list var output differently

[Fuenzy]

What I mean is, I want a list var to send like this

"1, 2, 3"

Instead of

"1, 2, and 3"

My code kinda bad but here it is:

options:
    useperm: "plugins.see"
    
    
command /plugins [<text>] [<text>]:
    trigger:
        player does not have permission "@useperm":
            send "Plugins (1): &a37"
        arg-1 is not set:
            player has permission "@useperm":
                {plugins::*} is set:
                    send "Plugins (%{count}%): &a%{plugins::*}%"
                else:
                    send "Plugins (0):"
        else if arg-1 is set:
            player has permission "@useperm":
                arg-1 is "add":
                    arg-2 is set:
                        {plugins::*} does not contain arg-2:
                            add 1 to {count}
                            add arg-2 to {plugins::*}
                        else:
                            send "Plugins (): Hey, you already added this one buddy."
                    
                    else:
                        send "Plugins (): Hey, you forgot to add the name lol"
                else if arg-1 is "remove":
                    arg-2 is set:
                        {plugins::*} contains arg-2:
                            subtract 1 from {count}
                            remove arg-2 from {plugins::*}
                        else:
                            send "Plugins (): Hey, that does not exist stupid!"
                    else:
                        send "Plugins (): Hey, you forgot to add the name lol"
                            
                    

on tab complete of "/":
    clear tab completions

Not sure where in your code the problem is, but here is an example of how you can do that:
Change:

command /test:
  trigger:
    send "{var::*}"

to

command /test:
  trigger:
    set {_temp} to "%{var::*}%"
    replace all "and" with "," in {_temp}
    send "%{_temp}%"
