Forum:Stamping Destruction chain

I was caught in a situation and need help deciding what would happen when faced with the same situation in a later duel.

The situation was that I had Masked Dragon in attack position and my opponent had 2 face-down spell/trap cards on the field. I activated Stamping Destruction from my hand targeting the face-down spell/trap card on my left. My opponent responded by activating the Quick-Play spell card on my right which was Book of Moon and selected my Masked Dragon. We had gotten into a debate on weather or not my Stamping Destruction's effect would resolve.

Is it true that Stamping Destruction would not be able to resolve because a face-up dragon no longer exists on my field?
