Please combine total Relaxation with Ontspannen kun je leren;...

[Trisha]

Hello can someone combine the following books for me. I can't combine them:
* Ontspannen kun je leren; Basisboek met CD voor mind, body & spirit - John Harvey (english title is Total relaxation)
* Total Relaxation: Healing Practices for Body, Mind & Spirit [With CDROM]
by John Harvey

The books are the same, only the first one is a Dutch edition.
I don't know why I can't combine them.

Thank you very much.

You could not combine because the author's name was not identical. Fixed and combined under John R. Harvey as per cover.
