craft :123: attempt to index? (a function value) --Please help!

When I run my program with 'rednet' off, it's fine. However, when i run the program with 'rednet' on, it terminates and gives me this error: craft :123: attempt to index? (a function value) –Please help! craft is my program name :D/>/>
This is the code:

local fl = turtle.getFuelLevel()
local rn = false
--Functions
function forward(num)
  for a = 1,num do
  turtle.forward()
end
end
function shiftLeft()
  turtle.turnLeft()

end
function shiftRight()
  turtle.turnRight()
  forward(1)
  turtle.turnLeft()
end
function fuel()
  textutils.slowPrint("Current Fuel level: "..fl)
  if fl == 0 then
  textutils.slowPrint("Please add coal to slot 1")
end
end
function rprompt()
  write("Enable rednet? y or n :")
  check = io.read()

  if check == "y" then
  rn = true
  else if check == "n" then
  rn = false
  end
end
end
function prompt()
  write("How many pickaxes would you like to craft?:")
  input = read()

  write("What material would you like it to be made of? - Diamond/Gold/Iron :")
  input2 = read()

  print("Crafting "..input.." "..input2.." pickaxes")
end
function sticks()
  turtle.refuel()
  forward(3)
  shiftLeft()
  forward(1)
  turtle.suckUp()
  turtle.dropUp(turtle.getItemCount(1) - 2 * input)
  turtle.transferTo(6,turtle.getItemCount(1)/2)
  turtle.transferTo(10,turtle.getItemCount(1))
end
function materials()
  turtle.back()
  turtle.turnRight()
  forward(1)
  if input2 == "diamond" then
  forward(1)
  else if input2 == "gold" then
  forward(3)
  else if input2 == "iron" then
  forward(5)
  end
end
end

  forward(1)
  turtle.suckUp()
  turtle.dropUp(turtle.getItemCount(1) - 3 * input)
  turtle.transferTo(2, turtle.getItemCount(1) - 2 * input)
  turtle.transferTo(3, turtle.getItemCount(1) - turtle.getItemCount(1) / 2)
end
function craft()
  turtle.back()
  turtle.turnLeft()
  if input2 == "diamond" then
  forward(1)
  else if input2 == "gold" then

Help will be much appreciated!

rednet. You called one of your functions rednet, and you cannot do that, because it makes the computer think you are trying to overwrite the rednet api. Thus, when you call rednet.open() in the rednet function, it looks for a value within the rednet function named open(), not the api.
