trigger to input text in custom field when case is created

Hi all,
writing my first trigger and can't seem to get it to work, can you take a look and see what I am doing wrong? Should it be after insert, before update?
It's just not putting the test text in the custom field...
What i am trying to do is eventually put a template in the description field for my users to fill out.

trigger insertText on Case (before insert, before update) {

            for (case c : {
                        If (c.triggertest__c == null)
                                    c.triggertest__c = 'Text here';

                        else {
                                    System.debug ('field is already filled in');

Dear David,

You have to trigger the trigger before insert and before update if you want to assign a value to same record or you wanna put some custom validations. 

The code you have mentioned should work. Try to add OR condition in if block like following
If (c.triggertest__c == null ||  c.triggertest__c == '')

Hope it helps you. Let me know if need help.
