I'd like to do the following but I am running out of ideas.

I'd like to validate the requesters organizational role with the aim of showing/hiding fields on the ticket form.

For instance, if a requester is a member of the Organizational Role "Line Manager", they would be presented with different fields than someone who was not in said role.

I would like to do this by code, but as yet, I have not found the correct script terms to use.

Any help would be most welcome.

I'd very very disappointed if this were not possible as it makes these "Organizational Roles" pretty impotent if not.
