Newbie to salesforce and looking for a way to write a trigger that will create 11 line items for when a field is update.  Object is credit request and when this is saved would like multiple credit lines to be added which is also an object.  Below is a rough start, but looking for guidance.  Picture attached showing what I would like to see after the request is saved and line items automatically created.


trigger TestCreditLinesAdd on Credit_Request__c (after insert)
{
    List<Credit_Lines__c> creditlines = new List<Credit_Lines__c>();  
        
    for(Credit_Request__c cr :  trigger.new)
    {
      creditlines.add(new Credit_Lines__c(.Quantity__c = 0.001));
    }          
        
	insert creditlines;
    
}
