I'm trying to get Calvin to move to my town, and have finally grown all the lettuce, unlocked the side area where the frame is. I have the rusty yellow bell in my hand, but it only lets me "check" the frame, it never seems to trigger the event of the hanging of the frame. Has anyone else had that problem? I've tried to hang the bell over and over again at least twenty five times, I've left and come back to the area... Please help!
