Hi, 

I am working on an LWC mini-project "Airline Ticket Booking". I want a button by which the user can add as many passengers as he wants for the purpose of ticket booking. How it would be possible? Please give me an appropriate link so that I can learn.

Hi getting error when trying to delete a recourd wher record owner != logged in user below is my code 

trigger MobDiscount on Mobile__c (before insert,before update,before delete) {
Trigger :     
    if(Trigger.isinsert == true)
    {
        DiscountForMobiles.DiscountNewCoustomer(Trigger.new);
    }
    
    if(Trigger.isupdate == true)
    {
        DiscountForMobiles.DiscountOldCoustomer(Trigger.new);
    }
    
    if(Trigger.isdelete == true && Trigger.isbefore == true)
    {
        DiscountForMobiles.OwnwerAloneCanDelete(Trigger.old);
    }
    
}

            If(SingleCoustomer.Brand__c == 'Samsung')
            {
                
               SingleCoustomer.Price__c = SingleCoustomer.Price__c * 10/100;
               SingleCoustomer.Discount_Status__c = '10 % Discount';
