Input field Question

Ok, I have a simple form on a .SWF and wanted to change the background color of the input fields. I found a message here showing me how to do it:

For some reason, now the input fields echo the following lines:

_level0.form.email

(or when viewing from browser: _level0.container.form.email)

All I did to configure the input fields was to add the following:

email.background=1
email.border=1
email.borderColor=0x3E3022
email.backgroundColor=0xB6A289

Any ideas?
