Custom Go button path with space

I have created numerous custom buttons, using the GO command, that are just paths to go to local, and network folders. However, whenever there is a space in the path Opus returns an error. For example, this button
Go K:\My Dropbox
returns a can not find path error message. I have deduced that the space in the path must be the problem. I could solve the problem by changing the folder name but that is not always practical when dealing with third party folders such as Dropbox, Media Center, or My videos.

How do I deal with the space in the path? Thank you.

Put double-quotes around the path.

That did it! Thank you.
