Pulling from specific categories

First off -- fabulous extension! Thank you so much!

Now my issue...I'm not new to Joomla, but I am new to custom MySQL coding. I'm trying to create content grids that contain articles from specific categories.

So, for example, I have "News" articles. On the news page, I want to create a grid that has the Title, Created Date and Summary only from the category NEWS. I've been able to create the table, but it either pulls ALL my content (not just the news) or NONE of my content.

What query do I need to use to pull from specific categories? Do I use that query in the "Additional Conditions" area?

Thanks!

I figured it out! For those newbies with the same issue, I used this command in the Additional Conditions area:

(catid = '45') OR (catid='46')

45& 46 were the two categories I wanted articles pulled from to populate my column of "news" articles.

Thank you again!
