Life in MiniatureDon't Sweat the Small Stuff!

I am looking for a movie about a house that has an attic, and one of the walls has a magical door that leads..?
to a dollhouse, like another world. A girl who used to visit all the time returns to the house and discovers her friend has gone missing. She find that she has become a china doll in the dollhouse. When trying to rescue her she almost becomes a doll herself.

I know this movie but the name has left me. It's either a Disney, Nickelodeon, or family channel movie from a while back...6-10 years?

Its not Coraline, its much older.

Thanks
