[Slice]

Luckily I was on a caffeinie buzz.
What you did wrong was create an empty variable called "cmdtext" then use it. The variable called "params" contains the command string except for the first part.
I think this should work:

pawn Код:

COMMAND:r( playerid, params )
{
    if ( isnull( params ) )
    {
        SendClientMessage( playerid, -1, "USAGE: /r [text]" );
        
        return 1;
    }
    
    new
        UnitIdentifier[ 512 ],
        playername[ MAX_PLAYER_NAME ]
    ;
    
    GetPlayerName( playerid, playername, sizeof( playername ) );
    
    UnitIdentifier = dini_Get( "UnitIDs.txt", playername );
    
    new erpstring[ 128 ];
    
    if ( PlayerTeam[ playerid ] == Team_Sheriff || PlayerTeam[ playerid ] == Team_LVPD || PlayerTeam[ playerid ] == Team_Fire )
    {
        if ( dini_Exists( "UnitIDs.txt" ) )
        {
            if ( strlen( dini_Get( "UnitIDs.txt", playername ) ) != 0 )
            {
                GetPlayerName( playerid, playername, sizeof( playername ) );
                
                format( erpstring, sizeof( erpstring ), "(DCPCOM) %s %d: %s, over.", UnitIdentifier, playerid, params );
                
                SendMessageToLaw( erpstring );
            }
            else
            {
                GetPlayerName( playerid, playername, sizeof( playername ) );
                
                format( erpstring, sizeof( erpstring ), "(DCPCOM) Unit %d: %s, over.", playerid, params );
                
                SendMessageToLaw( erpstring );
                
                SendClientMessage( playerid, COLOR_YELLOW, erpstring );
            }
        }
    }
    
    return 1;
}
