My code has a flaw. But I dont know how to fix it?

You didn't set the MaxActivationDistance back, as I assume you meant to.

function onClicked(player)
game.Players:FindFirstChild(player.Name).leaderstats.Coins.Value = game.Players:FindFirstChild(player.Name).leaderstats.Coins.Value + 100
game.Players.thenasafarouk.leaderstats.Coins.Value = game.Players.thenasafarouk.leaderstats.Coins.Value + 20
game.Workspace.FarmButton.ClickDetector.MaxActivationDistance = 0
game.Workspace.WheatSix.Transparency = 1
game.Workspace.WheatFive.Transparency = 1
game.Workspace.WheatFour.Transparency = 1
game.Workspace.WheatThree.Transparency = 1
game.Workspace.WheatTwo.Transparency = 1
game.Workspace.WheatOne.Transparency = 1
wait(60)
game.Workspace.WheatSix.Transparency = 0
game.Workspace.WheatFive.Transparency = 0
game.Workspace.WheatFour.Transparency = 0
game.Workspace.WheatThree.Transparency = 0
game.Workspace.WheatTwo.Transparency = 0
game.Workspace.WheatOne.Transparency = 0
game.Workspace.FarmButton.ClickDetector.MaxActivationDistance = 0 -- I assume this should be something else?
end
script.Parent.ClickDetector.MouseClick:connect(onClicked)
