Using multiple arguments for a dig program

Title: Using multiple arguments for a dig program

I want to use the same program to dig up, down and forward. It always gives me the error message that I put after the last else even though I type: dig forward 4

local args={...}
local arg1=args[1]
local arg2=args[2]
if arg1 == forward then
  for i=1,tonumber(arg2) do
    turtle.dig()
    turtle.forward()
  end
elseif arg1 == down then
  for i=1,tonumber(arg2) do
    turtle.digDown()
    turtle.down()
  end
elseif arg1 == up then
  for i=1,tonumber(arg2) do
    turtle.digUp()
    turtle.up()
  end
else
  print("Usage: dig forward/up/down amountofblocks.")
end

Split into new topic.

you forgot quotations around your strings when comparing them

local args={...}
local arg1=args[1]
local arg2=args[2]
if arg1 == "forward" then --here
  for i=1,tonumber(arg2) do
	turtle.dig()
	turtle.forward()
  end
elseif arg1 == "down" then --here
  for i=1,tonumber(arg2) do
	turtle.digDown()
	turtle.down()
  end
elseif arg1 == "up" then -- and here
  for i=1,tonumber(arg2) do
	turtle.digUp()
	turtle.up()
  end
else
  print("Usage: dig forward/up/down amountofblocks.")
end

Thank you very much.
