OpenURL: Error message Improper statement

Trying to use OpenUR with the following but I get an error message.
ZC with Google Apps
url points to a document on Google Drive in the apps domain
url will work in Safari
Document is shared with anyone in the domain for viewing

openUrl( https://drive.google.com/a/homesold.pro/file/d/0Bxt4E-nnZA0cUUVpc1BESTNpUnFPSzBMaXlZMVBPbkVqUk5r/vie","New window");

Thanks for any assistance
