Playlist Editor: Index not selecting track

[RocketMan]

In the Track field of the Playlist Editor, if a DJ enters a numeric value that is a valid track index for the album, it is being saved as the literal number rather than the track. Example:

https://zookeeper.stanford.edu/?action=viewListById&playlist=44792

Expected: A numeric value that corresponds to a valid track index should select the corresponding track from the album.
