Access won't allow index property change

[Sadie Hewgill]

I don't know why, but I have created an index and now can't set any of the properties for it. It has multiple values, but I have tried setting indexes with one values, and still the properties options are greyed out. There is no place to enter yes/no for uniqueness. Any suggestions as to what is wrong? I used to be able to change the properties, but not anymore.
