I have pasted example below
code:
function ck() {
//assigning variables
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getActiveSheet();
var lastrow = ss.getLastRow();
var valsr7 = sheet.getRange(lastrow, 3).getValue();
var valsr30 = sheet.getRange(lastrow, 4).getValue();
var valsrn = sheet.getRange(lastrow, 5).getValue();
var valINC7 = sheet.getRange(lastrow, 6).getValue();
var valINC30 = sheet.getRange(lastrow, 7).getValue();
var valINCn = sheet.getRange(lastrow, 8).getValue();
var service = sheet.getRange(lastrow, 2).getValue();
var now = new Date();
var wk = now.getWeek();
//now assigning values to variable
var A = valsr7;
var B = valsr30;
var C = valsrn;
var D = valINC7;
var E = valINC30;
var F = valINCn;
var AB = AB;
if (service == 'Global-Servicenow-Support-T2' && A ==0 && B == 0 ){

if(service == 'Global-Servicenow-Support-T2' && A == 0) and if(service == 'Global-Servicenow-Support-T2' && B == 0) and if (service == 'Global-Servicenow-Support-T2' && A ==0 && B == 0 )
Please help i want single output when i pass condition if (service == 'Global-Servicenow-Support-T2' && A ==0 && B == 0 ).

Answer 1

Change condition
if(service == 'Global-Servicenow-Support-T2' && A == 0){
to
if(service == 'Global-Servicenow-Support-T2' && A == 0 && B != 0){
and change condition
if(service == 'Global-Servicenow-Support-T2' && B == 0){
to
if(service == 'Global-Servicenow-Support-T2' && B == 0 && A != 0){
Then you will have one output for if (service == 'Global-Servicenow-Support-T2' && A ==0 && B == 0 )
