Review of personal code - google-apps-script

Question

I found this code and implemented it into my spreadsheet. My problem is that the code overwrites some data validation I had in my empty list. I wish to keep that drop down menu since I want the users to have it as easy as possible. I thought I could add the lines below (see text between **)
function onEdit(event) {
// assumes source data in sheet named Masterlist
// target sheet of move to named Actionlist
// test column with yes/no is col 13 or M;
var ss = SpreadsheetApp.getActiveSpreadsheet();
var s = event.source.getActiveSheet();
var r = event.source.getActiveRange();
if(s.getName() == "Masterliste"
&& r.getColumn() == 13 && r.getValue() == "Ja") {
var row = r.getRow();
var numColumns = s.getLastColumn();
var targetSheet = ss.getSheetByName("Actionlist");
var target = targetSheet.getRange(targetSheet.getLastRow() + 1, 1);
// **
var cellrange = SpreadsheetApp.getActive().getRange(target);
var range = SpreadsheetApp.getSheetByName("Dropdown").getRange('A16:B18'); //This is the range for the dropdown I want to hand over.
var rule = SpreadsheetApp.newDataValidation().requireValueInRange(range).build();
cell.setDataValidation(rule); //Include a data validation menu in each line automatically
// **
s.getRange(row, 1, 1, numColumns).copyTo(target); //This executes the copy order with the data provided before
}
}
I know this might be easy for some of you but I have just started with google 4 months ago and it's driving me crazy. I am familiar to excel and VBA, but not to Java at all.
Yes I did already do the codeacademy courses. They really didn't help me a lot. Sorry for my tone I am getting really annoyed by this. Thanks for your help. Enjoy the weekend!

You need to add an option to copyTo. Here is what that looks like:
s.getRange(row, 1, 1, numColumns).copyTo(target, {contentsOnly:true});
Alternatively you could use: copyValuesToRange(sheet, column, columnEnd, row, rowEnd)
