Change the value of a field based on the selection in another field - In a FORM

Hi,

This question is based on using a Form for entering data.

I was wondering if I can change the value of a field based on the selection in another field. e.g. If I select TBD in a dropdown it will show a red flag.

I have a field with a default White Flag - I need to flip it to Red as a warning if a user is entering data that will be flagged later.

I need to use a TBD as they may not have the data on hand and it is an indicator to get it - otherwise I would simply only give them valid options in the drop down :)

All I can seem to do in the Form is show fields or not.
