Input text fields: Initial values

Hi there,

I am creating a flash user input form and want to have some initial values in each Input text field (i.e. - ‘First Name’, ‘Email Address’ etc).

I know I can simply type these values into the Input text fields in the .fla movie, but doing this means the user has to delete the initial value before entering their own details.

Which leads me to to my question:

How do I make the initial values automatically disappear when the user clicks their mouse on the Input text fields?

Thank you in advance,
the chad
