This line:

pawn Код:

if(sscanf(params,"ui",facname)) return SendClientMessage(playerid,COLOR_RED,"Usage:/clancreate [clanname]");

should be replaced by

pawn Код:

if(sscanf(params,"s[39]",facname)) return SendClientMessage(playerid,COLOR_RED,"Usage:/clancreate [clanname]");

And also, the error line:

pawn Код:

format(pInfo[playerid][facname], 39, facname);
