I need help! i explain more in the desc

I want the character grows up when strength every time the strength is adding +1 but it doesnt grows This is the script

local children = game.Players:GetChildren()
for i = 1,  #children do
	local humanoid = children[i].Character.Humanoid
	humanoid.HeadScale.Value = children[i].leaderstats.Fuerza.Value/50 - 1
	humanoid.BodyHeightScale.Value = children[i].leaderstats.Fuerza.Value/50 + 1
	humanoid.BodyWidthScale.Value = children[i].leaderstats.Fuerza.Value/50 + 1
	humanoid.BodyDepthScale.Value = children[i].leaderstats.Fuerza.Value/50 + 1
end

Assuming that is the entire script, you need to put the for loop in a Heartbeat event:

local children = game.Players:GetChildren()
local runService = game.RunService
runService.Heartbeat:Connect(function()
	for i = 1, #children do
		local humanoid = children[i].Character.Humanoid
		humanoid.HeadScale.Value = children[i].leaderstats.Fuerza.Value/50 - 1
		humanoid.BodyHeightScale.Value = children[i].leaderstats.Fuerza.Value/50 + 1
		humanoid.BodyWidthScale.Value = children[i].leaderstats.Fuerza.Value/50 + 1
		humanoid.BodyDepthScale.Value = children[i].leaderstats.Fuerza.Value/50 + 1
	end
end)

This will ensure that the loop continues to run as long as the game is running.
