[support] display/hide a cck text field based on the input cck date field

[Francesco]

Hi again,
a typo to fix and a note I forgot to add:

> - a Date field named "due_date"

the above was of course "duedate", as the mentioned code states:

> $due_date_timestamp = strtotime($node->field_duedate[0]['value']);

As for the note, you can see that the timestamp is created parsing a
string. This means that you are not obliged to use a Date field - a
plain text field will be fine - but using the Date module will ensure
the date validation in first place.

My code might not work if the string passed to strtotime is not
correctly formatted. Be sure to feed it a correct time format.

Have a nice day,
Francesco
