Access Help with Access 2013 - changing a form field back colour based on another fields entry (Check box)

[Pauline Kelly]

Hi I wonder if anyone can help. I want the back colour in an organisation name field to change to green if they are a member company based on a "member yes no" check box field......is this possible. I am pretty good with access generally but conditional formatting and code are not something I know much about. Any help gratefully received. PS both fields are held in the same form and table.

Thank you
