[ut2k4] How do I make 4 rounds 2mins each?

[legacy-GELLYHEAD]

I'm trying to make a new game type that by default has 4 rounds each of which is 2 minutes long

I've tried changing the NumRounds in my own extended gametype but that doesn't seem to work

The round shouldn't end if the goalscore is reached but INSTEAD only change after the 2 minutes are up

any help would be greatly appreciated

thanx
