Noob Lua question about an error

[Velgarth 0]

If I put this code into a computer, 

local component = require("component")
local nrg = component.ie_lv_capacitor.getEnergyStored():int
print(nrg)

, I get the error 

/tmp/eh:3: function arguments expected near 'print'

Could someone please tell me what I am doing wrong here?

I have OpenComputers and Immersive Engineering loaded

The ":int" at the end of your 2nd line is causing the error.  The documentation shows you the returns/expected params that way, but you don't include them.
