Really stooooooopid n00b question

[Bink]

First of all, Yes I know I spelled Stupid wrong.

My Question is, when I do a shoot, I like to work in both Manual Focus and Auto Focus to ensure I get the picture I want. (Im starting out) ANYWAY, I was working with Twins this past weekend, and some of the photos i took in Auto, would only focus on or girl or the other.. OR the focus would be completely on something OTHER than the girls... BUT when i was taking the pic, it looked focused any pointers on why it does this? Or how to get it to not do it? Obviously i know working in manual would fix that but even some of my manual's i thought I was focused in the view finder and I really wasn't...

Thanks

Have you tried selecting your focus points manually to focus where you want to.

An indication of camera body and focus mode used would be helpful. Of course, we could keep playing the guessing game.

I have a Nikon D3100, And I was using my 55-200mm Lens in Auto.

Go to page 60 of this http://www.nikonusa.com/pdf/manuals/noprint/D3100_ENnoprint.pdf Camera's Manual it will explain how to choose selective focusing there.
