Why do I keep getting this error?

[Azarias547]

Every time I try to run my game it gives me an error saying "expected then near ="

this is my program (I'm sure there's lots of other bugs). I'm still very new to lua, so I wouldn't be too surprised if it's something really simple.

 

 

Script.Damage = 0 --int "Damage per interval"

Script.Interval = 0 --int "Damage Interval"

Script.Safety = false --bool "safe"

 

function Script:Collision(entity, position, normal, speed)

if(entity:GetKeyValue("Safe") == true) then

self.saftey = true

else

self.safety = false

end

end

 

function Script:UpdateWorld()

if self.saftey == false

if(DamTaken == true)then

DamInt = Time:GetCurrent() + self.Interval

end

Now = Time:GetCurrent

if DamInt < Now then

NewHealth = (entity:GetKeyValue("health")) - self.Damage

entity:SetKeyValue("health") = NewHealth

end

end

end

if self.saftey == false

 

missing a then at the end
