Turtle Help

Hey I was making a program to have a turtle detect a tree then cut it down even when I am away but I get the error bios:206: [string "startup"]:12:'<eof>' expected

The code is:
x = 0
while true do
term.clear()
term.setCursorPos(1,1)
write("Waiting")
textutils.slowPrint("…")
sleep(0)
if turtle.detect() == false then
sleep(1)
end
end
elseif turtle.detect() == true then
break
end
end
x = 0
term.clear()
term.setCursorPos(1,1)
textutils.slowPrint("Cutting…")
turtle.dig()
turtle.forward()
while true do
x = x + 1
turtle.digUp()
turtle.up()
if turtle.digUp() == false then
break
end
end
while true do
x = x - 1
turtle.down()
if x == 0 then
turtle.back()
turtle.drop()
os.reboot()
end

Not sure why it won't show the spaces but there are spaces

You ended this if statement prior to the elseif.

change

while true do
term.clear()
term.setCursorPos(1,1)
write("Waiting")
textutils.slowPrint("...")
sleep(0)
if turtle.detect() == false then
sleep(1)
end
end
elseif turtle.detect() == true then
break
end
end

to

while true do
term.clear()
term.setCursorPos(1,1)
write("Waiting")
textutils.slowPrint("...")
sleep(0)
if turtle.detect() == false then
sleep(1)
elseif turtle.detect() == true then
break
end -- ends if statement
end -- ends while loop
