Google Sheets Script: Finding date from variable in a range - date

Question

This is my first attempt at script. I'm pretty familiar with VBA. I have a date in A1 in the "Day" Sheet. I have a range of dates in column A on the "Monthly" sheet. I'm trying to find todays date on monthly sheet (from the variable on "Day" sheet) and paste the data there. I can't get past this first step of finding the date row. Basically the manager will have a form ("Day" Sheet) and when he hits the save button it will enter the data on the "Monthly" Sheet and it will clear the form. At the bottom I showed the execution log and it says -1.0 for the Index. Seems like it should say 2.0. Any help is much appreciated!
function moveValuesOnly () {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var activeSheet = ss.getSheetByName("Day");
var reportSheet = ss.getSheetByName("Monthly");
var todayDate = activeSheet.getRange("A1").getDisplayValue();
var lookupRangeValues = reportSheet.getRange(2,1,32,1).getDisplayValues();
var index = lookupRangeValues.indexOf(todayDate);
/*
//cash on hand
activeSheet.getRange("I2").copyTo(reportSheet.getRange("C" & index),SpreadsheetApp.CopyPasteType.PASTE_VALUES,false);
//POS Readout
activeSheet.getRange("B3").copyTo(reportSheet.getRange("B" & index),SpreadsheetApp.CopyPasteType.PASTE_VALUES,false);
//Waste or free pizza
activeSheet.getRange("B5").copyTo(reportSheet.getRange("N" & index),SpreadsheetApp.CopyPasteType.PASTE_VALUES,false);
//Dough made
activeSheet.getRange("B6").copyTo(reportSheet.getRange("L" & index),SpreadsheetApp.CopyPasteType.PASTE_VALUES,false);
//Total expenses itemized
activeSheet.getRange("A10:G15").copyTo(reportSheet.getRange("I" & index),SpreadsheetApp.CopyPasteType.PASTE_VALUES,false);
*/
Logger.log(todayDate);
Logger.log(lookupRangeValues);
Logger.log(index);
}

Answer 1

-1.0 index means that the todayDate was not found on your lookupRangeValues. This is because lookupRangeValues is basically a 2d array and indexOf() is not applicable here. You should create a loop to find the index/row of todayDate. With this, you can replace your line of code with indexOf() to this loop:
for(var row in lookupRangeValues){
if(lookupRangeValues[row][0]==todayDate){
var index = row;
break;
}
}
