Help using farm-building program

I know this is an old topic, but I was trying to use your program in Minecraft 1.7.10 using Computercraft 1.65. My world is using fuel off if that matters, but I have tried it with fuel on as well. I have named the program "fb". Every time I run the program I get the following, then nothing happens:

Plenty Building Blocks, Thanks!
fb:32: attempt to compare string with number expected, got string

This is split from here.

The issue is that your fuel-disabled setup means that turtle.getFuelLevel returns "unlimited", which isn't a number. You'll either have to re-enable fuel or modify the program to check for "unlimited" as well as a sufficiently large amount of fuel.

Thanks for the reply, but as I stated i am getting the same error when I turn the fuel requirements back on.

Nevertheless, the only way for the specified line to error in that way is to have fuel turned off. Odds are your attempt to re-enable it failed - to do so, you'd need to shut down the game (or server, if you're using one), edit its config, then restart it.

Or you could alter that line to correctly deal with a string response:

if type(turtle.getFuelLevel()) == "string" or turtle.getFuelLevel() >= NeededFuel then
