Using JavaScript with True/False Buttons

Status Update: Feeling accomplished and defeated.  I fear that my 1st build in SL is a lot bigger than I anticipated.

Math's arrays worked perfectly for the names of the selected items. However, along with the name of the items, I would like the nutritional values of the selected items to also be listed. This is where I ran into trouble.

In the example below, Soda and Lemonade both have 0 protein and 0 fats. Instead of these numbers showing up in both columns in list form, they are hidden.  I know its because this section of Math's script:

if(findEntryIndex(listArray,newValue)== -1){
listArray.push(newValue);
}else{
removeEntry(listArray,findEntryIndex(listArray,newValue));
}

Is there a way that I can adjust Math's array to list the duplicate values of selected items?

If not, I think the next step may be for me to do as Phil shared:

...if you wanted to fix what you have I would have added the triggers to a layer and added a trigger to reset concate variable and show the layer each time you click a checkbox...

I am just unsure how to go about this since I have (4) variable for each food item. 

Walt, thank you for the outline! If there isn't a fix for me at this point, I'll rebuild this whole course per your direction and see where I end up.

Thank you again in advance!

    Im not 100% sure what your problem is Christine, but i do think its as easy as creating separate arrays for the nutritional values... eg. create a list/array for Proteins and push/remove/read the values from there....

    Quickly added it as sample here...

    /*
    So now we need to find and delete the selected value from the Storyline variable
    */
    var player = GetPlayer();
    var listArray=[];
    var proteinArray= [];
    var StorylineList = player.GetVar("listArray");
    var StorylineProteinList = player.GetVar("proteinListArray");
    var newValue = player.GetVar("newValue");
    var newProteinValue = player.GetVar("newProteinValue");

    if(StorylineList!=""){
    listArray = StorylineList.split(",");
    }
    if(StorylineProteinList!=""){
    proteinArray = StorylineProteinList.split(",");
    }
    if(findEntryIndex(listArray,newValue)== -1){
    listArray.push(newValue);
    }else{
    removeEntry(listArray,findEntryIndex(listArray,newValue));
    }

    if(findEntryIndex(proteinArray,newProteinValue)== -1){
    proteinArray.push(newProteinValue);
    }else{
    removeEntry(proteinArray,findEntryIndex(proteinArray,newProteinValue));
    }

    var cleanArray = uniq(listArray);
    var cleanProteinArray = uniq(proteinArray);
    player.SetVar("proteinListArray",cleanProteinArray.toString());
    player.SetVar("listArray",cleanArray.toString());
    player.SetVar("displayList",cleanArray.join("<br />"));
    player.SetVar("proteinDisplayList",cleanProteinArray.join("<br />"));

    function uniq(a) {
    return Array.from(new Set(a));
    }

    function findEntryIndex(_array,_string){
    return _array.indexOf(_string);
    }

    function removeEntry(_array,_index){
    return _array.splice(_index,1);
    }

     

    Do use a proper Javascript enabled texteditor. Although Storyline's editor is improved now, it still is quite inferior to editors like Sublime Text and Brackets.
