title: Error 201 select identifier must be declared
body: <p>I am trying to make a login form through Oracle's Form Builder, I have a table called TRAVEL_USER which I made in SQLPlus.</p>
  
  <p>I have made a button and am using the trigger WHEN-BUTTON-PRESSED.</p>
  
  <p>To start myself off I am using this code to simply count the number of users registered on the system:</p>
  
  <pre><code>DECLARE
      TUsers NUMBER := 0;
  BEGIN
      SELECT COUNT(*) FROM TRAVEL_USER;
  END;
  </code></pre>
  
  <p>When compiling this I get the following error:
  Error 201: identifier 'TRAVEL_USER' must be declared.</p>
  
  <p>I can confirm that this table exists in the database I am connecting to, I checked via SQLPlus and the data block wizard in the Oracle Forms Builder.</p>
  
  <p>I connect to the database with full admin privileges (using the system username).</p>
