Differences between getRange, getDataRange, and getActiveRange?

Question

If it isn't immediately apparent by the question, I am pretty new to Google Apps Script. I'm trying to write a Spreadsheets function that runs through each row of a form submission sheet in a workbook and update a second sheet/range (in the same workbook) based on the values of the cells in the first using a for loop. However, nothing happens when I run the function.

I'm pretty sure the error is in how I'm defining the ranges in question, but I'm not 100% sure. Here's a modified version of what I've written:

function update() {
  var ss = SpreadsheetApp.getActiveSpreadsheet();

  var secondSheet = ss.getSheets()[1];
  var submissionSheet = ss.getSheets()[0];

  var secondRowEnd = secondSheet.getLastRow();
  var submissionRowEnd = submissionSheet.getLastRow();

  var secondColumnEnd = secondSheet.getLastColumn();
  var submissionColumnEnd = submissionSheet.getLastColumn(); //used to define ranges dynamically

  var secondRange = secondSheet.getValues();
  var submissionRange = submissionSheet.getValues();

  for(var i = 2; i <= submissionRowEnd; i++) {

    var rock = secondRange.getCell(i, 1).getValue();
    var paper = secondRange.getCell(i, 2).getValue();
    var scissors = secondRange.getCell(i, 3).getValue();

    var status = secondRange.getCell(i, 4).getValue();
    var forStatus = secondRange.getCell(i, 5).getValue();

    if (status === "Do X!") {
      for(var j = 2; j <= submissionRowEnd; j++) {

        var jrock = submissionRange.getCell(j, 1).getValue();
        var jpaper = submissionRange.getCell(j, 2).getValue();
        var jscissors = submissionRange.getCell(j, 3).getValue();
        var jstatus = submissionRange.getCell(j, 4).getValue();

        if (status === forStatus) {
          jrock.setValue(rock);
          jpaper.setValue(paper);
          jscissors.setValue(scissors);
        } else { /*do nothing*/ }
      }
    }
  }

I've been staring at slightly different versions of this code for weeks now, so any and all eyes on this would be greatly, greatly appreciated!

Just checkout out the Apps Script API reference for the Spreadsheet Service. All the functions are documented there. Here are links to descriptions of the methods you need:

• Spreadsheet.getActiveRange()
• Sheet.getDataRange()

getRange() has multiple implementations.

• Sheet.getRange(row, column)
• Sheet.getRange(row, column, numRows)
• Sheet.getRange(row, column, numRows, numColumns)
• Sheet.getRange(a1notation)
