What exactly is happening when you try.
Do you have the equivalent iWork apps for the type of documents that you are trying to upload installed on your iOS devices.

As I mentioned you can't do what you want through iCloud.com because you need to open the documents on an iOS device before they can be downloaded to a mac again.
If you want to upload documents that aren't for use with iOS devices this User Tip might be of interest.
