Could I please get help with "for i = X, X do"

I'm trying to make a mining turtle clear a Eleven by Eleven area but I can't figure out how to redo sections of code a number of time.

There's the pastebin of my code, what am I doing wrong here? Could someone please help me out here?

You really aren't doing anything wrong (minus the "end" on the last line that shouldn't be there), except digging in a spiral pattern is much more difficult than if you were digging in a zig-zag pattern.

local function digIfDetect()
	if turtle.detect() then turtle.dig() end
end

for i=1, 11 do
	for ii=1, 11 do
		digIfDetect()
		turtle.forward()
	end

	if i%2 == 0 then
		turtle.turnLeft()
		digIfDetect()
		turtle.forward()
		turtle.turnLeft()
	else
		turtle.turnRight()
		digIfDetect()
		turtle.forward()
		turtle.turnRight()
	end
end

The "digIfDetect()" part is only so that it doesn't try to dig empty blocks.

Thank you very much!

I'll edit it as per your suggestions and update this post with the details

Nevermind! i got it! thank you!
