Coding help needed!

var originalCost = "itemCost";

var newPrice;

var discount = "discount";

onEvent("startBtn", "click", function( ) {

  setScreen("calculator");

});

onEvent("itemCost","click", function() { 

  getNumber;

});

onEvent("continue","click", function() {

  setScreen("calculate2");

});

onEvent("calculate","click", function() {

  setScreen("price");

  calculate();

  setText("finalPrice", newPrice);

});

onEvent("resetBtn","click", function(){

  reset();

});

/// something isnt working here, I keep getting NaN "not a number as my result when i calculate"

function calculate() {

 percentage();

 newPrice = originalCost - (originalCost * discount);

}

function percentage() {

  discount = discount/100;

}

function reset() {

  onEvent("resetBtn","click",function() {

    setScreen("calculator");

  });

}

I am working on an app for my AP Computer Science Principles Create Portion, and I cannot get the app to run without the end result number showing as NaN, which I assume means “Not a Number”. If anybody could help that would be amazing.

I am so tired right now and I had to create this for my AP CompSci class and for whatever reason I legitimately thought this was peak humor.

09/12/17 I left my laptop to go take a shower and came back to my cat using it as a heater. She then growled when I tried to move her. School is still out because of Hurricane Irma, but I'm safe! There was no damage to my school, so I return tomorrow. All of my instructors have implemented extension plans, except for one, who apparently thinks you can write an essay through a hurricane. Happy Tuesday and, if your area is still flooded, stay safe!

09/05/17 In love with this infographic I made a couple weeks ago for AP Computer Science Principles! It took me a little while to get good at these but I'm finally getting it! Please don't repost without credit!

Array-2 > centeredAverage

Array-2 > bigDiff

public int bigDiff(int[] nums) {  int min = nums[0]; // declare variables to hold values to double check  int max = nums[0];

 for (int i = 0; i < nums.length; i++)  {    min = Math.min(min, nums[i]); // checks between current min and value at i    max = Math.max(max, nums[i]);  }  return (max - min); // returns int value of difference }

Array-2 > countEvens
