LyX ⇒ Change Appearance of Citation in Harvard Style

[woogidc]

I'm a newbie to LyX. When I try to put citation on my work with Havard style, the output looks like Goddard[2001]. This makes it very difficult to look at my sentence as it looks like continuous from my sentence.

How to change this from Goddard[2001] -> to (Goddard 2001).

I'm importing reference from JabRef on Windows7. Can natbib change this?

Thank you in advance.
