Moving rows in 'Complete' status to another sheet in Google Sheets - google-apps-script

Question

I'm trying to add a script to my sheet that would help to keep in cleaner by moving all completed rows from 'Main' sheet/tab to 'Completed' if the row is in the 'Complete' status. Filtering unfortunately isn't enough.
I was hoping it's something I can figure out on my own but have been running into errors when running the script I modified. Not sure if it's the right one. Could anyone point me towards a correct script?
Any guidance would be much appreciated.
Here is the example sheet:
https://docs.google.com/spreadsheets/d/1dGm-XddcndmvwcP-K61OViLpNTcMmKpI2rEQOYpVuJQ/edit?usp=sharing
Here is the script I found and tried to modify to my own sheet but still got errors when renamed sheets and edited ranges:
function onOpen() {
var ui = SpreadsheetApp.getUi();
ui.createMenu('Custom Menu')
.addItem('doneCopy', 'doneCopy')
.addToUi();
}
function doneCopy() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheetByName("Current");
var values = sheet.getRange(1, 8, sheet.getLastRow(), 1).getValues();
var moveRows = values.reduce(function(ar, e, i) {
if (e[0] == "DONE") ar.push(i + 1);
return ar;
}, []);
var targetSheet = ss.getSheetByName("OLD");
moveRows.forEach(function(e) {
sheet.getRange(e, 1, 1, sheet.getLastColumn()).moveTo(targetSheet.getRange(targetSheet.getLastRow() + 1, 1));
});
moveRows.reverse().forEach(function(e) {sheet.deleteRow(e)});
}

Answer 1

There are three syntax errors in your code:
the name of the source sheet
var source = ss.getSheetByName("Main")
the name of the target sheet
var target = ss.getSheetByName("Completed")
the value to match
e[0] == "Complete"
function doneCopy() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheetByName("Main");
var values = sheet.getRange(1, 1, sheet.getLastRow(), sheet.getLastColumn()).getValues();
var moveRows = values.reduce(function(ar, e, i) {
if (e[0] == "Complete") ar.push(i + 1);
return ar;
}, []);
var targetSheet = ss.getSheetByName("Completed");
moveRows.forEach(function(e) {
sheet.getRange(e, 1, 1, sheet.getLastColumn()).moveTo(targetSheet.getRange(targetSheet.getLastRow() + 1, 1));
});
moveRows.reverse().forEach(function(e) {sheet.deleteRow(e)});
}
