Repeater gives me errors, but works. Whats going on?

[Harmster]

Hey,

I started on my tag system with repeaters... It works, but I get a bunch of errors... And I've got no idea what the problem is. These are errors in the session->error and I've put them in a JQuery plugin called toastr.

It looks like this:

What can I do to change this? Or is this only in debug mode and it doesn't really matter?

Are those errors or just notices?
