The only problems I had was trying to figure out how to change the background color. The video explained how, but the instructor had already had his photoshop format set, so I had to google it and open a new photoshop project and click on background instead of the white I had previously had set from the last project.
As I started getting the colors block, I had forgotten to change my brush size to soft when I started blurring. I also had a problem when I tried to cut and copy the two layers. I could do the blurred but when I tried to do top one, it kept saying the area was empty. I realized that I needed to select that layer on the right hand side before I could cut and copy it.
