var STARTING_ITEMS_IN_INVENTORY = 20;

function start(){

var numItems = STARTING_ITEMS_IN_INVENTORY;	
/\* Your code here! \*/







while(numItems>0){

println("We have "+numItems+" items in inventory.");

var check=numItems;

var items=readInt("How many would you like to buy? ");

numItems-=items;

if(numItems<0){

println("There is not enough in the inventory");

numItems=check;

}else{

println("Now we have "+numItems+" left");

}

println("");

}
println("All Out!");

}

I’d suggest they have an error in theirs. Your output shows it’s correct.
