Incorect config

I want to blacklist the Rocket launcher, Snowball Gun and Multiple Grenade Launcher. I keep getting errors with this config. Could you please show me the proper config to use for these 3 weapons? Even putting just Rocket Launcher in the first spot Rocket launcher wouldnt be blacklisted. Thank you
