Expected ')' (to close '(' at line 2), got 'end'?

Strange way of hooking up the touch event. neverless, the way you've formatted it is slightly squeed, you need to close the if statement with a then

Like:

if script.Parent.Touched:Connect(function(Hit) -- if statement and event function start
        if Hit.Parent:FindFirstChild("Enemy") then
            Hit.Parent.Enemy.creator.Value = script.Parent.Firer.Value
        end
    end)  then needed since the if statement doesnt have a then word
-- code that will only run once the script loads since this event hookup happens once the script loads!

end -- end of if statement

A better and a more coherent(straight forward) way of doing this is the following:

local TouchedEvent = script.Parent.Touched:Connect(function(Hit) 
        if Hit.Parent:FindFirstChild("Enemy") then
            Hit.Parent.Enemy.creator.Value = script.Parent.Firer.Value
        end
    end) -- touched event end

local timesrun = 0

if TouchedEvent then -- just to show this is only run once!, that's unless this is in some form of loop.
    print("Touched event hooked up!")
    timesrun = timesrun+1
    print("timesrun = "..(timesrun))
end

You dont need to hook up the event top a value since just calling script.Parent.Touched:connect(function(Hit) end) is good enough to get the job done.

Final correct way to do this code:

script.Parent.Touched:Connect(function(Hit) 
    if Hit.Parent:FindFirstChild("Enemy") then
        Hit.Parent.Enemy.creator.Value = script.Parent.Firer.Value
    end
end) 

hope this helps! :)

You have an extra end. You have two if statements, but 3 ends This is how your code should look like.

if script.Parent.Touched:Connect(function(Hit)
        if Hit.Parent:FindFirstChild("Enemy") then
            Hit.Parent.Enemy.creator.Value = script.Parent.Firer.Value
        end
end)
