The problem is you have too many ends. If you post your code, we can help you pinpoint where.

But, it usually comes from a misunderstanding of an if block. Occasionally we all add an extra end, but that's usually the case.

sue thing the code is


rednet.open("right")
s, m = rednet.receive()
if m == "home" then
for i = 1, 38 do
   turtle.up()
   end
end
if m == "dig" then
for i = 1, 19 do
   turtle.digDown()
   turtle.down()
   turtle.digDown()
   turtle.down()
   end
end
if m == "back" then
   turtle.back()
   end
end()
if m == "left" then
   turtle.left()
   turtle.forward()
   turtle.right()
   end
end
if m == "right" then
   turtle.right()
   turtle.forward()
   turtle.left()
   end
end
if m == "forward" then
   turtle.forward()
   end
rednet.close("right")

You've got lots of ends too many. For every 'if' block, change this:


if m == "right" then
   turtle.right()
   turtle.forward()
   turtle.left()
   end
end

To:


if m == "right" then
   turtle.right()
   turtle.forward()
   turtle.left()
end

You'd also want to look into the 'ifelse' statements.

Edit: also, you've got a typo (I think) here:


if m == "back" then
   turtle.back()
   end
end()

remove the parentheses:


if m == "back" then
   turtle.back()
end

rednet.open("right")
s, m = rednet.receive()
if m == "home" then
for i = 1, 38 do
   turtle.up()
end
if m == "dig" then
for i = 1, 19 do
   turtle.digDown()
   turtle.down()
   turtle.digDown()
   turtle.down()
end
if m == "back" then
   turtle.back()
end
if m == "left" then
   turtle.left()
   turtle.forward()
   turtle.right()
end
if m == "right" then
   turtle.right()
   turtle.forward()
   turtle.left()
end
if m == "forward" then
   turtle.forward()
end
rednet.close("right")

you just need to end your for loop, add another end before line 13

haha. Orwell did most of the help here. you may want to consider giving him a +1, I don't know what the general belief is but I think that's reasonable

I realize that I didn't help at all, but that's why we're here, is to help beginners. I started programming just a few months ago. Now I know Java, C, C#, Objective-C, Lua, and am working on C++. You'll get there a lot faster than you think. :P/>

We all suffer bouts of transposition at times.
