How Do I stop A Script From Giving Me stuff when I reach a number?

I don't get why everyone who answered this overlooked this....

local value = game.Players.LocalPlayer.Character:WaitForChild("SmallLeft").Value 

^^ This here will save the value for example it is 3

The PROBLEM is when you add +1 it will still output 3, that's because the value variable wont change and you have to get it each time again.

local small = script.Parent
local value = game.Players.LocalPlayer.Character:WaitForChild("SmallLeft")
local max = 3
small.MouseButton1Click:Connect(function()

    if value.Value < max then -- you've also switched < and >
    print("+1")
    value.Value += 1
    else
        print("max")


    end

end)

Your code has errors such as using greater than instead of less than. The following code should work if it is in a LocalScript:

local small = script.Parent
local value = game.Players.LocalPlayer.Character:WaitForChild("SmallLeft").Value
small.MouseButton1Click:Connect(function()
    while value<=3 do
        print("+1")
        value+=1
    end
    print("max")
end)

You can do this with a for loop and use the maxValue variable as the parameter

local small = script.Parent
local value = game.Players.LocalPlayer.Character:WaitForChild("SmallLeft").Value 
local max = 3

small.MouseButton1Click:Connect(function()

for i = 1, max , 1 do
    game.Players.LocalPlayer.Character:WaitForChild("SmallLeft").Value += 1
end

end)
