Basic Trigger Question

This is probably a piece of cake for most people, but I am having trouble getting a simple trigger to work. I want to analyze a table that is populated and then subsequently used in the same batch process.

I want to analyze it after an insert or delete, but am getting the following error. I would appreciate someone showing me the errors of my ways.

SQL> CREATE OR REPLACE TRIGGER TR_MYTABLE   2 AFTER INSERT OR DELETE ON MYTABLE   3 BEGIN
  4 ANALYZE TABLE MYTABLE ESTIMATE STATISTICS SAMPLE 30 PERCENT;   5 END;
  6 /

Warning: Trigger created with compilation errors.
