How do I make a custom field required?

Question

I have been trying to change my custom field from no (not required) to yes (required) but the system will not take my change. The custom field is website property. But I did notice that I cannot change any of the fields required selection. My guess is that I am trying to do this from the wrong screen?

Any ideas? Please see screenshot

Field configuration schemes control if the field is required or not. If you mark it required it will be required upon creation.  A field configuration scheme is made up of one or more field configurations so you can require different fields for each issue type.
