I think the ''incorrect number of argments'' error you encountered is related to the way you entered the data on your cp. I've tried it (that same question/example)on my cp and the answer I got is exactly the same as the solution that they have there.I don't think it's a software issue.By the way, uploading the screen shot can give us a clear picture of what's going on.
