textarea

hello
I’m tiring to get the values of a (textbox, radio buttons, and a combo box) and combine then in to a hidden textarea.

For example after someone sets these variable
http://www.pretendreality.com/add.php

location - combo box and displays a list of countries
sex - radio button has two options male and female
name - textbox where the user can enter there name

it would change a hidden textarea to
"location: [Canada], sex: [male], name: [funvill]"
Does that make any sense?

Thanks for your help
