Please help with: Nancy Drew Shadow at Water's Edge.?

I'm almost to the end of the game. I'm playing on junior level, and i'm in the secret bathrooms. I have completed the large monogram (i think that is it) on the wall, and the picture resembles a fox. But nothing happened! I did it multiple times, I even checked an online walk through and mine matches up perfectly. Nancy won't say anything though! No "i got it!" or anything. I would like to know what I could doing wrong that isn't allowing me to continue on in the game. Thank you so much! This is so frustrating.
