Why is it saying I clicked the button?

So I'm trying to make a button for my game to declare war between two countries, and I have a part for each country. So I put a ClickDetector in each part, and here's my script so far:

function activatefalse() script.Parent.ClickDetector.MaxActivationDistance = 0 end if game.StarterGui.Controls.WarButton.MouseButton1Click then script.Parent.ClickDetector.MaxActivationDistance = 999999999999 end

When I run it, the click detector's max distance is already 99999999 even though I didn't click the button yet.

MouseButton1Click requires a function after

game.StarterGui.Controls.WarButton.MouseButton1Click:Connect(function()

You accidentaly checked for the existence of the event instead of listening for the event. You need to set MouseButton1Click as an event using Connect like this:

function activatefalse() 
  script.Parent.ClickDetector.MaxActivationDistance = 0 
end
game.StarterGui.Controls.WarButton.MouseButton1Click:Connect(function()
    script.Parent.ClickDetector.MaxActivationDistance = 999999999999
end)

I tried using the function for the mouse button click but it didn't change.
