Google Scripts copyto issue - google-apps-script

Question

I am trying to get a row with a certain range to copy into the row after text ends. I had it working a few days ago, but cannot figure out where I am going wrong right now.
So far I have:
function getNextRow();
return SpreadsheetApp.getActiveSpreadsheet().getLastRow()+1;
}
function test() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var range = ss.getRange('a4:e4')
var data = range.getValues();
var nextrow = getNextRow();
ss.getRange(nextrow).setValues(data);
}
I have attempted the copyto, but cannot seem to figure it out again from the google developer's page. Any help is appreciated, thank you!

Answer 1

For one thing, you never specify the sheet you are working with. Which sheet of the spreadsheet should this script act on? Use getActiveSheet to pick the active one, or getSheetByName to pick a particular sheet.
Also, your function getNextRow returns an integer, which is the number of the first row that's below all the data. So far so good. But then you call ss.getRange(nextrow) where nextrow is that integer... not good. This isn't one of the acceptable ways of using this method: it needs either A1 notation, or (row, column) pair of integers for a single cell, or (row, column, number of rows, number of columns) quadruple for a range of more than one cell. Which is what you have, so use
ss.getRange(nextrow, 1, data.length, data[0].length).setValues(data);
This says: starting in the row nextrow, column 1 (meaning A), select the range of same size as data. The pair data.length, data[0].length is how one gets the height and width of data array.
That said, there is an easier way to achieve what you want, using appendRow method. Here's a function that would replace all of your code:
function test() {
var sheet = SpreadsheetApp.getActiveSheet();
var range = sheet.getRange('a4:e4')
var data = range.getValues();
sheet.appendRow(data[0]);
}
This appends the content of A4:E4 in the active sheet to the bottom of the same sheet. The method appendRow takes a one-dimensional array, hence data[0] and not just data (which is two-dimensional).
