How do i set another players variable with a uuid in it to a number?

[HypixelIsIdiotic]

so im making a strength smp plugin but im trying to make a setstrength command. The part where it sends something to the player works well but the variable wont change. Heres my code:

command /setstrength [<player>] [<integer>]:
permission: op
trigger:
set {strength::%arg-1's uuid%} to arg-2
send "&cSomeone Set Your Strength To %arg-2%!" to arg-1

Edit: there is proper spacing it just doesnt show. That isnt the error.
edit 2: also it says there isnt an error in minehut

Remove [] between arguments to force the user to fill in the argument
Debug
Use offline player instead of player
