When I followed the steps in this Try It Out example and I attempt to run this example by clicking on the check box the panel does not display as it should. I have attempted this exercise several times with the same result. I am using IE 7 and I think I have followed all of the steps correctly, however, I am new to this language.
Thank you for your help.
