"Manual scale boundaries not set."

I am a SW guy. I am using a cUrl command in a Windows 7 Pro computer to execute this:
curl -s "http://radmon.org/radmon.php?function=submit&user=MyID&password=MyPW&value=nn&unit=CPM"
RadMon replies with a success status of 200 and the message of "Manual scale boundaries not set."

I fill in the ID, PW, and nn with the appropriate values.

Does the boundaries message come from RadMon? What does it mean?

I am not running the RadMon.org code on my computer. I am registered and the data I send shows up on the RadMon map web page. I filled out the registration info on the RadMon.org web site.

Thanks for any and all help.
