Hello,
I can't seem to remember how to create a field in a custom contact form!

The custom form contains a field on who is responsible for the contact and
each user has views filtering to show only 'their' contacts.
I want to create a 'Temp' field with a Yes/No value (checkbox).
I want to use this field to create another filtered view.
Any user can use this if and how they want; to filter out whom to call this
week,
who gets Xmas card, which contacts are personal/private etc.
I need a field inside the form to easily create the filtered view, don't I?
Or is there a better way?

Grateful for any tip!
Thankx in advance,
kk
