Combining two scripts into a google sheets addon - google-apps-script

Question

EDIT thanks for the assistance, I've updated the script as follows, however it still will not create a submenu from the Add-on menu.
// Hide empty rows in PRINT sheet
function onOpen(e) {
var menu = SpreadsheetApp.getUi().createMenu('Print Ready');
menu.addItem('Print Ready', 'PRINTREADY');
menu.addToUi();
}
function PRINTREADY(){
var shname='PRINT';//<<<<<<<<<<<<<<<change to appropriate sheet name
var rw1=4, rw2=258;
var s, nrws, data, i;
nrws=rw2-rw1+1;
s=SpreadsheetApp.getActiveSpreadsheet().getSheetByName(shname);
data=s.getRange(rw1, 1, nrws, s.getLastColumn()).getValues();
s.showRows(rw1, nrws);
for (i in data) if (data[i].every(function(x) {return x=='';})) s.hideRows(1*i+rw1);
}
// Sort PANTRY LIST A-Z
var sh = SpreadsheetApp.getActiveSheet();
if( sh.getName() == "PANTRY LIST" ) {
var editedCell = sh.getActiveRange().getColumnIndex();
if(editedCell == 1) {
var range = sh.getRange("PANTRY LIST!A3:Z");
range.sort({column: 1});
}
}
I'm trying to deploy a sheets addon for some restaurant menu costing spreadsheets I have written. For some of the functionality I needed to include scripts, by themselves they are fairly straightforward:
Script 1: HideEmptyRows - this script hides empty rows to make the recipe ready to print, it should only run on a recipe document with a sheet name PRINT.
Script 2: SortList - this script simply sorts the sheet A-Z onOpen and every 15 minutes, it only runs on the Pantry List document with a sheet name PANTRY LIST.
They run fine individually as scripts, but when I combine them into a sheets addon Script 1 doesn't generate a menu, and I get Range Not Found errors from Script 2.
Script 1
function onOpen(e) {
var menu = SpreadsheetApp.getUi().createMenu('Print Ready')
menu.addItem('Make my recipe ready to print', 'PRINTREADY')
.addToUi();
}
function PRINTREADY(){
var shname='PRINT';//<<<<<<<<<<<<<<<change to appropriate sheet name
var rw1=4, rw2=258;
var s, nrws, data, i;
nrws=rw2-rw1+1;
s=SpreadsheetApp.getActiveSpreadsheet().getSheetByName(shname);
data=s.getRange(rw1, 1, nrws, s.getLastColumn()).getValues();
s.showRows(rw1, nrws);
for (i in data) if (data[i].every(function(x) {return x=='';})) s.hideRows(1*i+rw1);
}
Script 2
function onOpen(){
var sh = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
var editedCell = sh.getActiveRange().getColumnIndex();
if(editedCell == 1) {
var range = sh.getRange("PANTRY LIST!A3:Z");
range.sort({column: 1});
}
}
Does anyone know how to combine them into one script that I can deploy as an addon?
Thanks
