Problem NuRelm Get Posts

I’m hoping someone can help with this problem. I’m trying to include in a page the most recent 5 posts from a specific category. Inserting the necessary short code into the page causes the page content to disappear on the front end, even though it is still available from the admin/”edit page” side. If I remove the short code and republish, the page content then re-appears on the front end. I’m using “NuRelm Get Posts” Version 0.2 with WordPress version 3.1 (recently upgraded from version 3.0.5).

Here is the code I have tried, neither of which works:
[get_posts category_name=”things-to-do-2″ numberposts=5]
[get_posts category_name=”things to do” numberposts=5]

(Note: the category name is “things to do” while the category slug is “things-to-do-2”.)

Here is the page on which I would like the most recent, category-specific headlines to appear:
https://indianapolis-indiana.funcityfinder.com/indianapolis-things-to-do/

Any advice would be greatly appreciated. Thanks.
