You don't have any greater than , less than signs , apostrophes or semicolons
in the name?

Nothing. Just that space between the two words.

Spaces not allowed, did not catch that on your first post. The error message is
correct, xml names can not contain spaces. The property  name is used under the
covers as a name in an xml document which is why it must conform to the xml name
criterial.

I don't understand. Are you talking about the profile  name or
property name. I already created properties  with spaces,
ex: No project
and had no problems...

I should correct my last statement, Profile names are valid  with spaces - Base
Profile.... but field names for properties  show up as an error if there is a
space. I do not know right off what SP is on the specific machine I tested.

Property names is what I was working with. My systems do not accept property
names with spaces, same error message. You have a property  name that contains
spaces? I would guess profile  names are the same but have not tried.

With SP1 we were able to create  property names with a space. Since
SP2 we are not able to create new ones with spaces. The old ones
don't seem to be affected.
