Flash Components + Variable Names

Hi - any help appreciated on this one - I have been following the tutorial on this site “Flash Forms and Database Integration” it shows me how to use text input fields (made with the text tool), assign variable names to them and pass this to an ASP database.
I would really like to use MX 2004 components as I have to create a huge form for input into a database - but I cannot see where you put the variable names for each component??
Can anyone help???
