I forget that it is "--scrypt"

Much thank you very much 

Hi,

I am a newbie and I'm starting to mining Litecoin
I use the program "bfgminer-4.10.0-win32"

And using a bat file to run this command:
bfgminer -S opencl:auto -o stratum+tcp://litecoinpool.org:3333 -u ABC.1 -p 12345 --set-device intensity=9

But nothing I can not mining...
Does anyone know where I'm wrong please?
