Can u help me with Msg Centar for cod2?

[Minotaur]

Hello!
i have little bit a problem with setting msg centar for cod2...

i found on net lines for cfg and i put it, but server didnt write anything!
on net i find this lines:

//RD Msg Center Text Settings
seta sv_linerd1 " "
seta sv_linerd2 ""
seta sv_linerd3 ""
seta sv_linerd4 ""
seta sv_linerd5 ""
seta sv_linerd6 ""
seta sv_linerd7 ""
seta sv_linerd8 ""
seta sv_rddelay "45" // Time between msg's, must be >5 secs

so can u tell me why those lines dont work...
and can u tell me how to make those lines to write next maps from my rotate list?

thx for understanding
