Google forms list items with dynamic goto section - google-apps-script

Question

I found this answer posted here earlier.
function GoToPage() {
var form = FormApp.openById('MY FORM');
var spreadsheet = SpreadsheetApp.openById("MY SPREADSHEET");
var sheet = spreadsheet.getSheetByName("MY SHEET");
var list = form.getItemById("MY MULTIPLE CHOICE ID").asListItem()
var pagebreak01 = form.getItemById("PAGE BREAK ID 1").asPageBreakItem();
var pagebreak02 = form.getItemById("PAGE BREAK ID 2").asPageBreakItem();
var pagebreak03 = form.getItemById("PAGE BREAK ID 3").asPageBreakItem();
var choice1 = sheet.getRange("RANGE 1 FROM MY SHEET").getValues();
var choice2 = sheet.getRange("RANGE 2 FROM MY SHEET").getValues();
var choice3 = sheet.getRange("RANGE 3 FROM MY SHEET").getValues();
list.setChoices([
list.createChoice(choice1, pagebreak01),
list.createChoice(choice2, pagebreak02),
list.createChoice(choice3, pagebreak03)]);
}
when using a range larger than 1 in the choice# variables, this makes just one choice with all the items in the range separated by commas. how can I use this to make a list of choices that has a dynamic range?
My exact choices should be:
"** Add Location **" , goto newLocation section of form.
location 1, goto next section.
location 2, goto next section.
location 3, ect....
If you select new location and fill out the form to add a new location the script then adds that location name to the choices for the next time you fill out the form. so this list is continually growing larger.
function updateForm() {
var locationForm = form.getItemById("413015265").asListItem();
var equipmentForm = form.getItemById("2123556695").asListItem();
var newLocation = form.getItemById('231469190').asPageBreakItem();
var newItem = form.getItemById('90044295').asPageBreakItem();
var gotoIssue = form.getItemById('1493817332').asPageBreakItem();
var gotoLocation = form.getItemById('1425783734').asPageBreakItem();
var locations = tblLocations.getRange(2,2,tblLocations.getLastRow()-1,1).getValues();
var items = tblItems.getRange(2,2,tblItems.getLastRow()-1,1).getValues();
items = items.sort();
locations = locations.sort();
locationForm.setChoices([
locationForm.createChoice("** Add Location **",newLocation),
locationForm.createChoice(locations,gotoIssue)
]);
equipmentForm.setChoices([
equipmentForm.createChoice("** Add Item **",newItem),
equipmentForm.createChoice(items,gotoLocation)
]);
}
after running the above script I ended up with only 2 choices. 1 new location/item entry which works correctly, and 1 entry with all the current locations/items in the spreadsheet already, separated by commas. Can i just run a foreach loop inside the setChoices command?

function updateForm() {
var locationForm = form.getItemById("413015265").asListItem();
var equipmentForm = form.getItemById("2123556695").asListItem();
var newLocation = form.getItemById('231469190').asPageBreakItem();
var newItem = form.getItemById('90044295').asPageBreakItem();
var gotoIssue = form.getItemById('1493817332').asPageBreakItem();
var gotoLocation = form.getItemById('1425783734').asPageBreakItem();
var locations = tblLocations.getRange(2,2,tblLocations.getLastRow()-1,1).getValues();
var items = tblItems.getRange(2,2,tblItems.getLastRow()-1,1).getValues();
var locationChoices = [];
var itemChoices = [];
locationChoices[0] = locationForm.createChoice("** Add Location **",newLocation);
itemChoices[0] = equipmentForm.createChoice("** Add Item **",newItem);
items = items.sort();
locations = locations.sort();
for (var i=0;i<tblLocations.getLastRow()-1;i++){
locationChoices[i+1]= locationForm.createChoice(locations[i],gotoIssue);
}
locationForm.setChoices(locationChoices);
for (var i=0;i<tblItems.getLastRow()-1;i++){
itemChoices[i+1]= equipmentForm.createChoice(items[i],gotoLocation);
}
equipmentForm.setChoices(itemChoices);
}
I was able to figure it out. It's probably not the most beautiful solution but it works. :)
