function arguments expected

[Smellyzarg]

I get this error:
[gamemodes\soccer\gamemode\powerups.lua:47] function arguments expected near 'timer'

[lua]function ENT:EndTouch ( ent )
if ( ent:IsValid ()) and ( ent:IsPlayer()) then
self.Entity:Remove
timer.Simple ( 30, SpawnNewSpeed ) //Line 47

end
end[/lua]

I can't seem to find out whats wrong...
