How do I change the currency for open edx ecommerce

I am trying to set the price associate with a course via the ecommerce platform:

i.e. via url.com:18130/courses/new
(shown below)

I need to be able to change the currency to great british pounds or euros.
How can I do this?

You need to make use of Django admin panel to reflect the changes which you have made.

Thank you but this doesn’t seem to work
