Would my cooldown work in this case?

What is going on here? You’re returning something and then you have an if statement. This isn’t allowed.

I fixed it but I’m not sure if this is still correct

local TimeSinceFPress = tick()
local Cooldown = 5
function canUse()
	
	if TimeSinceFPress >= Cooldown then
		CanUseRightNow = true
	else
		CanUseRightNow = false 
	end
	
	return CanUseRightNow
end```

You Do Not Need To Return Anything

looks fine to me, what the return statement does is that it passes the specified values to whatever called the function and terminates that function
for example:

function foo()
	return 5 -- anything after this line in this function is invalid
end

local bar = foo()
print(bar) -- output: 5
