[Lua][Error] Attempt to Call Nil from attempted mining API

Title: [Lua][Error] Attempt to Call Nil from attempted mining API

I'm trying to get a simple mining API going to get my feet wet, but I seem to be handling something wrong is how I'm structuring the API. What it's supposed to do right now is just make a 3 deep, 4 long trench to test the API.

API 'tunnel'

function dig(Count)
repeat
while turtle.foreward() == false do
turtle.dig()
end
Count = Count - 1
until count <= 0
end

function mine(Count)
repeat
while turtle.foreward() == false do
turtle.dig()
end
turtle.digUp()
turtle.digDown()
Count = Count - 1
until count <= 0
end

Program

os.loadAPI("tunnel")
turtle.digDown()
turtle.down()
turtle.digDown()
turtle.down()
turtle.digDown()
turtle.down()
turtle.digDown()
tunnel.mine(3)

Split to new topic.

turtle.foreward() should be turtle.forward()
You just spelled it wrong, that's all.

It is turtle.forward not turtle.foreward.

You and your ninja brain.

Damnit. I should have believed my teachers in elementary school. Spelling does matter.
