Split into new topic.

Try `turtle.drop()` instead.

Try moving the while true do statement to the bottom of the program, so the drop function is above it, so the drop function is defined before the loop starts.

All source codes are read from top to bottom, here you're trying to call your drop() function before it has been defined.
You should try to get the habit to always define all your functions first, then do your main code after it.
And if I might add, instead of doing

turtle.select(1)
turtle.dropDown()
turtle.select(2)
turtle.dropDown()
...
...
turtle.select(16)
turtle.dropDown()

You should give "for" loops a try, like this

for slot = 1,16 do
turtle.select(slot)
turtle.dropDown()
end
