I have a form that includes a radio selection field with three options:

- Board Chair

- Executive Director

- Other

I then have an "Other" text field.  I have a workflow set up so the "Other" field is hidden when the form loads.  

What I want to have happen is to show the "Other" field when a user selects the "Other" option in the radio control.  I've tried six different ways to make this operational through workflows, and nothing seems to work.  I select "Other" on the radio selection, and the "Other" field remains hidden.

This seems like a really easy one, but for the life of me, I can't get it to work!

Thanks in advance!
