Function Inside of Enum will not work (Will not accept values ) but works when placed outside?

So I have created this Enum that contains the following values: 

case NewtonSeconds(Int)
case Thrust(Int)
case BurnTime(Int)

However, when I attempt to use this function:

func calculateNSeconds (thrust: Int, burn: Int) -> String {

RocketEngine.Thrust(thrust)
RocketEngine.BurnTime(burn)
var NSeconds = thrust * thrust * burn
RocketEngine.NewtonSeconds(NSeconds)
return "With a burntime of \(burn)s and a thrust of \(thrust)N, we get    a total of \(NSeconds) Newton-Seconds!"

}

I seem to get this error when attempting to run it:

RocketEngine.calculateNSeconds(50, 100) The error: Extra argument in call

Then, if I delete the second value I get this:

Type 'RocketEngine' does not conform to protocol 'IntegerLiteralConvertiable'

What am I doing wrong here? Please help.

Can you post the contents of the whole file please as these snippets don't provide the full picture.

With the full code listing we might be able to figure it out.

Thanks,
