Hello all...

Looking for some assistance on a trigger i'm writing...

Basically, I have a trigger that will update an Account Status and Stage (custom field) based on the completion of an Activity. I wrote the trigger initially based on the completed activity being logged on the Account record. When I realized I also needed to accomplish the same functionality if an activity is completed against a Contact (oopsies) within said Account, I modified the trigger to the below:

trigger changeAccountStagetask1 on Task (before update, after update) {
   
    Set<String> whatIDs = new Set<String>();
   
    for (Task tsk: Trigger.new) {
        whatIDs.add(tsk.whatID);
         } 
    List<Contact> conlist = [SELECT Id, AccountId FROM Contact WHERE accountId in :whatIDs];
   
    List<Account> filteredAccts = new List<Account>();
    Map<Id, Account> accts = new Map<Id, Account>();  
   
                                       
    Map<String, Task> taskMap = new Map<String, Task>();
    for (Task tsk: Trigger.new) {         
            if(taskMap.containsKey(tsk.whatId)) {      
            if(tsk.Status=='Completed' && tsk.Subject=='Call To Qualify (Successful)'){
                Account ld = new Account(Id=tsk.whatID);
                     ld.Status__c = 'Qualified Prospect';                             
                     ld.Stage__c = 'Need To Set Meeting';
                taskMap.put(tsk.whatID, tsk);          
            }
          
        }      
        update accts.values();
   }
   }

However, when I attempt to test this trigger in my Sandbox, nothing changes...whether I log the call on the Account, or on the Contact, the Status/Stage doesn't change...and no errors are coming up...any thoughts on what I'm missing based on my code above?

Thanks so much in advance for your help!!!
