I need a skript..

[CoolAlex4734]

Hi everyone! I'm currently in the process of making an awesome gen server, but I need a skript. Now I know how to use skript but I don't know how to make this skript so I'm coming out to you all! I just need Skript that let's you able to buy a rank voucher with Essentials Money, and the command is /shop. I wish I knew how to make this, but I don't. I hope you can make it for me!

on place of hay bale:
	set {gens::%location of event-block%} to uuid of player
	if {genscap::%player's uuid%} < 15:
		send ""
		send "&a&lYou place a &e&lWheat Generater"
		send ""
		add 1 to {genscap::%player's uuid%}
		while event-block is hay bale:
			wait 10 seconds
			drop 1 wheat above location of event-block
	else:
		cancel event 
		send "&c&lYou dont have any gen slot left"
		
on break of hay bale:
	remove 1 from {genscap::%player's uuid%}
	send ""
	send "&c&lYou broke a wheat generater"
	send ""
