Create Salesforce Trigger

You'll create a trigger in your instance and test it then send the code and installation instructions to me for use in the final client's system. You will not have access to the client Salesforce system. This should be a simple project for someone experienced with Salesforce triggers. The trigger you send must work in the client system. In order to encourage experienced coders and minimize endless back and forth, your code must work in the customer instance within the first 3 tries. It should work the first time, but there's two more just to be fair. The trigger is on activities. When an activity is created or modified, the trigger is fired. 1. The trigger looks at the WhoID value (contact that is linked ot the activity). i.e. 0036g00001J328SDAA 2. If the WhoID is not null, you lookup the Contact Name corresponding to that WhoID. At this point we have the name from the ID, i.e. John Smith 3. Store this value John Smith into Activity Field LinkedContact__c In English, we're just taking the contact name which is linked to an Activity (if there is one) and store that name in the text field LinkedContact__c. Error trapping should include no contact linked to activity, contact name missing from Contact, etc.
