Is there a way to identify multiple targets?

[topaz nebula]

Heya so I'm coding 3 menus that link together

Menu1: https://pastebin.com/5x01tyhq
Menu 2: https://pastebin.com/0vrYVgWj
Menu 3: https://pastebin.com/efKwPnSi

I tried to split both targets with a javascript but idk if it works since the command /menu (yourplayername) doesnt even work lets alone '/menu1 BoebaZakelijk\1y'

Im losing my mind trying to figure it out please help .. XD

Did you restart the server after adding register_command: true?
Why are you splitting the argument into 2 instead of making 2 arguments?
Also, you can't change the argument's value, even through js, so what you're doing won't work
