if == && if != make me confused.

            case 3:

            next;    

            mes .npc$;

            mes "Last broadcast user: ^FF0000"+.lastname$+"^000000.";

            next;

            mes .npc$;

            mes "Jail this player?";

            if(select("Yes:No")==2) continue;

            atcommand "@jailfor 15n "+.lastname$;

            announce .lastname$+" has been jailed for 15 minutes for abusing the Broadcaster NPC.",0;

            next;

            mes .npc$;

            mes "Player is jailed.";

            next;

            continue;

 

Is there a way to not allow the GM to use this case 3 if the .lastname$ isn't used yet aliases, null, blank because even without the .lastname it keep jailing and announcing.

"if == && if != make me confused."

 

To answer this...

 

== means equal to inside of a condition. Ex: "if .@container is equal to 3? Do .@container+1"

if( .@container == 3 ) { .@container++: }

&& is a way to extend the condition. It's like saying and. Ex: "if .@container is equal to 3 and .@package is equal to 4? Do .@container+1 .@package+2" 

if( .@contrainer == 1 && .@package == 4 ) { .@container++; .@package+=2; }

!= treat this like saying is not equal to. Ex: "if .@container is not equal to 3? Do .@container+1."

if( .@container != 3 ) { .@container++; }

Anyways I hope that helps a little. I don't have time for your other problem atm. :/
