how do i loop this?

i have this digging program called "diggy3" and i want to loop it a set number of times.
I'm new to coding and i can't figure it out.
The code is in the spoiler.

Spoiler

print("How many times would you like to run the program?")
local amountOfTimes = tonumber(read())
amountOfTimes > 0 do
turtle.dig()
turtle.forward()
turtle.turnLeft()
turtle.dig()
turtle.turnRight()
turtle.turnRight()
turtle.dig()
turtle.digUp()
turtle.up()
turtle.dig()
turtle.turnLeft()
turtle.turnLeft()
turtle.dig()
turtle.down()
turtle.digDown()
turtle.down()
turtle.dig()
turtle.turnRight()
turtle.turnRight()
turtle.dig()
turtle.up()
turtle.turnLeft()
amountOfTimes = amountOfTimes - 1
if amountOfTimes == 0 then
end

if i run this then i get this error (on the screen of my turtle):

bios:206: [string "diggy3"]:3: '='
expected

plz help and thanks in advance.

use a for loop,

print("How many times would you like to run the program?")
local amountOfTimes = tonumber(read())
for a=1,amountOfTimes do
turtle.dig()
turtle.forward()
turtle.turnLeft()
turtle.dig()
turtle.turnRight()
turtle.turnRight()
turtle.dig()
turtle.digUp()
turtle.up()
turtle.dig()
turtle.turnLeft()
turtle.turnLeft()
turtle.dig()
turtle.down()
turtle.digDown()
turtle.down()
turtle.dig()
turtle.turnRight()
turtle.turnRight()
turtle.dig()
turtle.up()
turtle.turnLeft()
end

you were very close this should work

print("How many times would you like to run the program?")
local amountOfTimes = tonumber(read())
while amountOfTimes > 0 do
  turtle.dig()
  turtle.forward()
  turtle.turnLeft()
  turtle.dig()
  turtle.turnRight()
  turtle.turnRight()
  turtle.dig()
  turtle.digUp()
  turtle.up()
  turtle.dig()
  turtle.turnLeft()
  turtle.turnLeft()
  turtle.dig()
  turtle.down()
  turtle.digDown()
  turtle.down()
  turtle.dig()
  turtle.turnRight()
  turtle.turnRight()
  turtle.dig()
  turtle.up()
  turtle.turnLeft()
  amountOfTimes = amountOfTimes - 1
  if amountOfTimes == 0 then -- not needed
  end
end

[edit] using a for loop is better for this as stated in the post above this one.

thank you for your help it works now and i understand lua a bit better.
