Hi Everyone, I was hoping I could get some insights as to what might be wrong with my trigger.  I have the following trigger I would like to run when a lead status within the lead is changed to a particular value.  When the value is changed, I would like to create a new activity on the lead record.  

Here is my code below, and the error I get back is:

Error: Compile Error: No access to entity: Activity at line 1 column 1

Any help would be greatly appreciated!

trigger createLeadActivity on Lead (after update) { 

    //make a set to hold opportunity ids that we need
    Set<Id> leadIds = new Set<Id>();
    
    for(Lead l : trigger.new)
        {
        //check to see if our field has been changed
        if(l.status != trigger.oldMap.get(l.Id).Status){
            
            leadIds.add(l.Id);
            
        }

       }
    
    if(!leadIds.isEmpty()){
        
       
        
        List<Lead> leadList = 
            [SELECT Id,Status
            FROM Lead
            WHERE Status = '4 - SAL Engaged' AND Id IN :leadIds ];
        
        
        
        for(Lead leadly: leadList){
        Lead led = new Activity();
        
       
        
        
       
        Activity newActivity = new Activity(Subject='LeadPassed',OwnerId=leadMap.get( record.WhoId ).OwnerId,Status='Not Started',Priority='Normal',WhoId=leadMap.get( record.WhoId ).id);

        ActList.add(newActivity);
        }
       
    }
