How many kids do you have?

Just got an email from Microsoft asking me to take a survey about the Zune at zoomerang.com. This is one of the last questions in it. Can you catch the dumbness in this before I tell you?

I have two kids that are 3 or younger, so naturally I selected 2 in that category and pressed continue. I Got an error saying I didn't answer completely, what the hell? I don't have any kids kids 4-7, 8-12 and 13-17 so does it expect me select the prefer not to answer option?

After reading a little closer I discovered the button text doesn't match the number of kids! Button 1 means 0 kids, button 2 means 1 kid, button 3 means 2 kids. WTF!?! I'm going to go out on a limb here and say whoever designed this is the dumbest person doing UI work.
