Upload Text and Multiple Images to Firebase - Android Studio

Question

How do you upload multiple images to firebase with a text file? I can upload the one image file find but once I add the second fileRef for the second image in the saveVehicle area it doesn't upload anything at all.

I have tried putting an if statement before the Storage Reference and still nothing.

EDIT: In the "private void saveVehicle()" section when I put in the code for "fileRef2" to save a secondary picture nothing happens. It does not upload to Firebase. Without "fileRef2" code the first image and texts saves fine. How do I save multiple images into one file?

Here is my code:
