I took a look at this and don't know how this show I am working on got there. I hope it can be fixed. Bryan LaHaise

The link samdog83 posted is the link that goes to your design tab. He just posted exactly what he was told to do by the note Joe made in case that big popped up again. It's okay Bryan. ;-)

Thanks Jennifer, it just made me nervous not knowing. It was funny seeing "invalid argument" Thanks again!

Thanks samdog and Jennifer. Sorry it made you nervous Sam.

You will definitely want to upgrade your browser, which should fix this. Internet Explorer is at version 9 now, and you are currently on version 7.

^ But just to let everyone know, I have a Windows XP computer, and the last time I tried upgrading to IE 9, it would not let me. It's only compatible with Windows 7 and maybe Vista. IE 8 works though (that's the one I currently have).

Thanks to all those who commented.
