Thunkable Timer

Hi guys, I am a little new to thunkable so I am still trying to figure things out. I did have a question though about the timer on thunkable. You see, I am trying to make it so that a little ship flies through meteors, and then a timer dings when it reached 10 seconds, making a button pop up saying, “congratulations, you passed” and then moving on to the next level. However I am unable to this, because, as I stated earlier, I am very new to these components and this website in general. Can you guys help?

The first block starts the timer by pressing a button. The second block executes nested commands after the timer expires. Configure the required parameters in the timer properties.
