Roll top desk

My wife recently\ acquired a roll top desk.

The roll top is hung up -- the slats do not fit into the groove on one side.

Try as I can, I can not slide the roll top over to engage the problem side.

The back and bottoms are enclosed so the adjustment has to be made from the exterior.

Before I try wedging it over, I'm inquiring whether anyone has any ideas about how to get it back in the track.

Thanks,

Jerry Bittne
