Half Life cheats not working

[leib10]

Decided after playing Black Mesa that I'd finish the story, so I reinstalled HL through Steam. I wanted to skip ahead and start in Xen, but I can't get the console to work. I've put in sv_cheats 1 and the console confirms the change, but I have tried to use various cheats to no avail. Any help on why this isn't working?

Enabled cheats doesn't take effect until you load or reload the map. It's best to do it in the menu before you start your game.

type restart or sv_restartround in the console,with previously enabled sv_cheats 1.It should work.
