Trying to get this function to run repeatedly

[Antiriver13]

I'm trying to get this code to run every ten seconds, but it will run the first time then not repeat
viewz = 0;
insanity = insanity or 0;
function insane()
for k, v in pairs(ents.FindInSphere( LocalPlayer():GetPos() + Vector(0,0,50), 200 )) do
if (v:IsNPC()) then
viewz = viewz + 1
print("+1")
if viewz > 1 then
insanity = insanity + viewz
end
end

if insanity > 100 then
insanity = 100
elseif insanity > 0 then
insanity = insanity - 1
end
if insanity == 100 then
print("You are insane")
print(insanity)
elseif insanity >= 85 then
print("You are almost insane")
elseif insanity >= 50 then
print("You are half insane")
print(insanity)
elseif insanity >= 25 then
print("You are a quarter insane")
print(insanity)
else
print("you are not going insane")
print(insanity)
end
end
end
timer.Create("idelay", 10, 0, insane())
it produces this in console
you are not going insane

what's on line 35?

You're passing the return of the `insane` function to timer.Create, you need to pass the `insane` function itself. That's why you're getting that error.
timer.Create("idelay", 10, 0, insane)
