Hello,

I have a trigger that is meant to update custom field on an Opportunity when specific tasks are created on an Account that is also linked to the Opportunity.  The trigger below saves and does not give any errors, however, nothing happens when a task is created.  Can anyone help me figure out why?  Thanks.

Trigger:

trigger MainTriggerTask on Task (after insert, after update, before delete) {
    
    IF(Trigger.IsAfter){
        IF(Trigger.IsInsert){
                ClassRenewalTasks updater6 = new ClassRenewalTasks();
                updater6.renewalTasks(Trigger.new);
        }
        
        IF(Trigger.IsUpdate){
            
                ClassRenewalTasks updater3 = new ClassRenewalTasks();
                updater3.renewalTasks(Trigger.new);
                
        }
    }

    ELSE IF(Trigger.IsBefore){
        IF(Trigger.IsDelete){
                ClassRenewalTasks deleteTsk = new ClassRenewalTasks();
                deleteTsk.deleteTasks(Trigger.old);

            }
    }
}

Class:

public class ClassRenewalTasks {

    public void deleteTasks(List<Task> delTasks) {
        List<Opportunity> linkedOpps = new List<Opportunity>();
        Map<Id, Task> taskMap = new Map<Id, Task>();
 
        for (Task t: delTasks) {
                taskMap.put(t.WhatId, t);
