Using JavaScript with True/False Buttons

Hello Walt and Math:

Thank you both for review.  I did not proofread my post and can see how it was unclear.  I have attached by Storyline file for review.

Essentially, when an item is picked, I would like it to appear in list form on a 'results' slide along with the item's nutritional values so that students can see their selections and proceed with questions following the exercise.

I've placed a table on my 'dessert' slide for the purposes of this post. In the example below, I have selected chocolate milkshake, fruit cup, and chocolate chip cookie.  These items appear in the table along with their nutritional counts.  This is exactly what I want to happen.

For each item, I have a combination of triggers and variables associated to a object checkbox (e.g. ChocChip).

Variables:

Triggers:

One Javascript trigger for the listing of items:

var player = GetPlayer();
var List_Dessert = player.GetVar("List_Dessert");
var ChocChip = player.GetVar("ChocChip");
var ChocChip_Button = player.GetVar("ChocChip_Button");
var Concate = List_Dessert + ChocChip;
player.SetVar("List_Dessert",Concate);

4 Javascript triggers for the listing of each nutritional value. Calorie listing example below:

var player = GetPlayer();
var List_Dessert_Calories = player.GetVar("List_Dessert_Calories");
var unitPrice = player.GetVar("ChocChip_Cal");
unitPrice = unitPrice.toFixed(0)
var displayPrice = unitPrice + "<br />";
var Concate = List_Dessert_Calories + displayPrice;
player.SetVar("List_Dessert_Calories",Concate);

The problem I am facing is, when items are unselected, they are added again to the table instead of being removed or not showing up. Here is an example below.

I don't know what the issue is so, your assistance is appreciated!

Lastly, referencing Math's comment:

Also be aware that variables in Storyline are always strings. So i do think the line in your code...
var Concate = List_Smash + Bacon;
is a bit weird. As i see it both List_Smash and Bacon are 2 text variables and all you do is adding them together. In fact the same as concat( ) does in Javascript but it would be good to use descriptive names as that makes life easier. So something like..
var breakfastString = List_Smash + Bacon;
would make more sense to me. You can always use this to detect what type a value is...
console.log("List_Smash is: "+typeof List_Smash);

I adapted all of my JS codes from this post:  https://community.articulate.com/discussions/building-better-courses/building-a-text-list-using-variables-9076700d-32e3-4351-b09c-0a333ae871cf.  So, if there is a better way of typing the JS command, please let me know.

Thank you both!
