JQuery validating with Firebug

JQuery validating with Firebug

When using JQuery in an app I am writing, (as the below shows), it produces several validation errors/warnings in the FireBug console.

Is anyone attempting to fix these and/or can anyone help me fix these ? I'm no JS guru (just give me the API !!!), but I'm willing to help/test/code where I can.
