Hi, this should work:

Code (Text):

1. command /dupe:
2.     description: Dupelicate
3.     trigger:
4.         if {cooldown::%player%} is not set:
5.             give player's tool to player
6.             add 60 to {wait_dupe::%player%}
7.             set {cooldown::%player%} to true
8.         else:
9.             message "&eYou Can't Dupe Now, You Must Wait %{wait_dupe::%player%}% Seconds!"
10.             stop
11.  
12.  
13.  
14. every second:
15.     loop all players:
16.         if {cooldown::%loop-player%} is not set:
17.             stop
18.         else:
19.             remove 1 from {wait_dupe::%loop-player%}
20.             if {wait_dupe::%loop-player%} is less than 1:
21.                 delete {cooldown::%loop-player%}
