Dynamic Helm Script Need Help

[Screwdriver]

Expectation:

Whisper npc:DynaUpper "21120" will change upper look to view id 920 or "21121" will change upper look to view id 921.

Script:

-[TAB]script[TAB] DynaUpper[TAB] -1,{
setarray @item[0],21120, 21121;
setarray @view[0],920, 921;
set @items, getarraysize(@item);
set @views, getarraysize(@view);
OnWhisperGlobal:
// == Helm Equipped
if(isequipped(21119)) {
if(@whispervar0$ == "@item[0], @item[1]") {
atcommand "@changelook 1 "+ @views +"";
 }
}
}

Could anyone lead me in the right direction? I'm probably completely off track in code, but I tried being correct.
