Noob here, what is wrong with my program?

My program is as follows:

turtle.getFuelLevel()
print("FuelLevel")
exit
end

I just started computer craft today so there may be some basic thing that I am not understanding.

Couple points:

1) Anything enclosed in quotes ("", '') is a string. Strings can be printed
2) exit is not needed
3) end is only needed if you have something to close (if statement, loop, etc.) (don't worry, I made the same mistake :P/>)

Assuming you want to print the current fuel level, or the value returned by turtle.getFuelLevel(), your program could look like this:

print( turtle.getFuelLevel() )

PS: When posting code on the forums, it's nice to use code tags.
