Add this ... or something like this..
set .requireditem,PODITEMID; // sets the itemId of the Proof of donation or required itemId for instant job
set .requiredqty,1; //sets the qty of the itemid needed for instant job
if(countitem(.requireditem)<.requiredqty) { mes "You need "+.requiredqty+" "+getitemname(.requireditem)+" "; }
Before this this if( ClassHelper == 1 || #ClassHelper == 1 ) end; the rest is up to you.
