Apt-get Error...???

[Larry Shields]

I am in need of some help on what I need to do to correct this error 
when I run apt-get update...

"GPG error: http://www.debian-multimedia.org sarge Release: The 
following signatures couldn't be verified because the public key is not 
available: NO_PUBKEY 07D563DI141B907"

Any help would be appreciated...

Thanks Larry
