[gears-users] could not create database: unknown object

[skunkwerk]

Hi,
   i'm just getting started with gears and am trying to create a local
database to start using.  i'm getting an error when trying to run the
code (below) saying "could not create database: unknown object."  i'm
not sure why this is happening, as i have gears installed, the samples
run fine, and the code is pretty much the same as what the
documentation states.  any ideas?

thanks

here's the relevant portion of code:
function init()
{
  var success = false;
  if (window.google && google.gears) {
    try {
          db = google.gears.factory.create('eurisko.database');
      if (db) {
        db.open('eurisko');
        db.execute('create table if not exists notes' +
                   ' (title varchar(255), content text, tags varchar
(255), timestamp int)');
        success = true;
      }
    } catch (ex) {
      alert('Could not create database: ' + ex.message);
    }
  }
}
