Hey! In the Opportunity Trigger question, It fails in the update context, you are actually overriding the value on the account with the new opportunity amount value. The other existing opportunity's amount aren't taken into consideration. Instead, we can collect the accountId's into a SET, query over AccountList : [Select id,amount,(Select id,amount from Opportunities) from Account where accountId IN: ] --> Loop over this list, get all the opportunity sum from subquery and add it to the account Amount, then update AccountList. Correct me if i am wrong. Thanks in advance.

Please post job openings also if any .

Upon deletion of the account all its contacts will get deleted automatically right. Then why do we need to delete the contacts ?

In updating total__c in account if you assign the value from your map then what If the total__c is already having a value? Instead of assigning the value from your map you need to add that value to the total__c current value. Correct me if I am wrong

For the trigger scenario I think there should be a Delete scenario as well. What you think?

Bro do you provide training
