Script: Using getHull() on stations returns nil

[lunerfox]

Working on a scenario where I wanted to trigger a message when a station's Hull is below a certain threshold.

--Orion 5 should tell you about the escaped scientist before being destroyed.
if Orion_5_stn:getHull() < 15 then
    print ("Orion 5 distruction is immedient. Hull at Orion_5_stn:getHull().)
end

Console prints this error message when function is called:

[ERROR] LUA: update: [string "scenario1.lua"]:390: attempt to call a nil value (method 'getHull')
