Here's the attachment:

As you can see, there were two people I had to edit into the picture! Now, just want to have the one daughter show and not have a white "mask".
The option to add a mask, as well as alpha channel is not clickable. Merge and Stack also not clickable... Clicking the eye on/off does not make her face show.

IT is because your picture is a jpg. You have to re-export it as a .png. Then you can add the alpha channel and make the white space transparent. I did it but my internet is going bonkers tonight and cannot upload it. I'll try tomorrow.

Any image format can be used.
You only need to upload the images needed to make the edit, by placing the person into the image.
So that would be 2 images, one of the person to be added and the image to place the person into.

Is this what you are wanting so you can stick the other picture underneath to show through the transparent space?

I think you need to resize her just big enough so the face sizes match in the back row then that will look great Conbagui.
She just looks a little smaller than she should.

...and pay attention to the lighting. There are plenty highlights on the main image.

a quicky..

Awesome! Combagui & rich2005 - these look great. My daughter's skin tone and hair (without the zig-zag I did) is more like the tone Combagui accomplished, but she does need to be scaled a bit larger. I think I could take it from here...Is there a way for me to obtain the file from you as an xcf to make some final adjustments? I'm happy to send the amazon card to you Combagui, as promised, if you provide me with a way to get it to you. Thank you so much!

@ 2ton, Yes, thank you. Although I am such a novice that I wouldn't know how to get her face to show without a tutorial. If you would like to pass it along to me I'll gratefully take it.
