How to add coma after the name of author?

Hello,

I wonder why Endnote write the reference as  (Smith 1999).

How can I change the settings f ENDnote  to put comma after the name of the author, something like:

                                                                    (Smith,1999)

Thanks

I am using the style of the journal:

Remote sensing of environment.

Also it the same case with 

(Smith and Gone 1999)

it should be:

(Smith and Gone, 1999) or (Smith & Gone, 1999)
