Dyanamic Dropdown List Validation (third level) using app script - validation

Question

I have a script written to apply three levels of validation. The first level of validation is in column A on the "master" sheet and the second and third are in the app script.
I am able to select the first level of validation in the "master"sheet and the list is filtered to only show the relevant answers in a dropdown list in Column B. After selecting my answer in Column B, the dropdown arrow appears in Column C but there are no fields to select. I can manually enter a value that is on my list and it is accepted and any thing that is not in the list is rejected. I have narrowed my issue to:
var filteredOptions = options.filter(function(o){ return o[0] === firstLevelColValue && o[1] === val });
When I place Logger.log(filteredOptions); in function applySecondLevelValadation(val, r){, it returns with an empty array [].
When I place
Logger.log(filteredOptions);` in `function applyFirstLevelValadation(val, r){
, it returns with the array:
[[Intermediate, 9:00 AM, Upper Dumont], [Intermediate, 12:00 PM, Outer Limts], [Intermediate, 3:30 PM, Satelite], [Intermediate, 9:00 AM, Box], [Intermediate, 12:00 PM, Hidden Valley], [Intermediate, 3:30 PM, Kermits]]
Screenshot of "options" sheet
Screenshot of "master" with all possible options for column A & B and no options for selection in column C
Any help figuring out why var filteredOptions = options.filter(function(o){ return o[0] === firstLevelColValue && o[1] === val }); is returning an empty array would be great!
Code being used:
var mainWsName = "master";
var optionsWsName = "options";
var firstLevelColumn = 1;
var secondLevelColumn = 2;
var thirdLevelColumn = 3;
var ws = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(mainWsName);
var wsOptions = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(optionsWsName);
var options = wsOptions.getRange(2,1,wsOptions.getLastRow()-1,3).getValues();
function onEdit(e) {
var activeCell = e.range;
var val = activeCell.getValue();
var r = activeCell.getRow();
var c = activeCell.getColumn();
var wsName = activeCell.getSheet().getName();
if(wsName === mainWsName && c === firstLevelColumn && r > 1) {
applyFirstLevelValadation(val, r);
} else if(wsName === mainWsName && c === secondLevelColumn && r > 1) {
applySecondLevelValadation(val, r);
}
}
function applyFirstLevelValadation(val, r) {
if(val === "") {
ws.getRange(r, secondLevelColumn).clearContent();
ws.getRange(r, secondLevelColumn).clearDataValidations();
ws.getRange(r, thirdLevelColumn).clearContent();
ws.getRange(r, thirdLevelColumn).clearDataValidations();
} else {
ws.getRange(r, secondLevelColumn).clearContent();
ws.getRange(r, secondLevelColumn).clearDataValidations();
ws.getRange(r, thirdLevelColumn).clearContent();
ws.getRange(r, thirdLevelColumn).clearDataValidations();
var filteredOptions = options.filter(function(o){ return o[0] === val });
var listToApply = filteredOptions.map(function(o){ return o[1] });
var cell = ws.getRange(r, secondLevelColumn);
Logger.log(filteredOptions)
applyValidationToCell(listToApply,cell);
}
}
function applySecondLevelValadation(val, r) {
if(val === "") {
ws.getRange(r, thirdLevelColumn).clearContent();
ws.getRange(r, thirdLevelColumn).clearDataValidations();
} else {
ws.getRange(r, thirdLevelColumn).clearContent();
var firstLevelColValue = ws.getRange(r, firstLevelColumn).getValue();
var filteredOptions = options.filter(function(o){ return o[0] === firstLevelColValue && o[1] === val });
var listToApply = filteredOptions.map(function(o){ return o[2] });
var cell = ws.getRange(r, thirdLevelColumn);
Logger.log(filteredOptions);
applyValidationToCell(listToApply,cell);
}
}
function applyValidationToCell(list, cell) {
var rule = SpreadsheetApp
.newDataValidation()
.requireValueInList(list)
.setAllowInvalid(false)
.build();
cell.setDataValidation(rule);
}

It looks like you are having an issue with the time column. Probably because it's comparing a string to a date or what have you. We would have more information if you shared a copy of the spreadsheet.
In any case, to avoid this, you can format data in both columns B (in 'master' as well as in 'options') as plain text (for that, go to Format > Number > Plain text in your spreadsheet). Then, you can write the trip times in 'options' as plain text.
I hope this is of any help to you.
