Creating an Action for Clipping Mask for Batch of Files?

Hello, I am rather new to Photoshop and am working on creating my first Action. The desired outcome would be:

Open an Image (we'll say a silhoutte of a dog)

Add another image to the document (we'll say a glitter pattern)

Add a clipping mask to the glitter pattern to mask it onto the dog

Save the finished project as a PNG

I've followed a few tutorials and when I follow the steps to create the Action, the clipping mask and saving the file work just fine. However, when I run the Action on several images (via Automate>Batch) , I run into a few errors. One, it repeatedly opens the original design that I used to record the action (IE the dog) and resaves it each time PS opens a new image from the designated Batch folder. Two, It does not add the clipping mask to the new designs that are in the Batch folder; it only resaves them as they already are (so just a silhoutte, no glitter clipping mask). And finally, it saves the design as a PS file, not as a PNG even though I added that to the Action when recording it.

Can anyone point in me in the right direction of how to correct this? I really appreciate your help!
