I made this code for a mining turtle. It is partially complete. When I run the function digDown() it tells me that the limit for that for loop must be a number.(line 35). I do not understand why it does not consider that variable a number.

You're not using for loops correctly. The PIL manual describes how the for loop is used in Lua. As of right now, you're using a boolean where you should have a number.
