I have an error message in the expression: "New expression variable name is invalid"

Hi,

I use NX8.0 and design a plastic part with expression draft. The error message
shows up: "New expression variable name is invalid"

How can I repair this?
Thx

What is the name of the expression?

Thanks John, the problem was solved next day. The reason was, that I used underscores "_" .So I understood
in newer versions of NX is this possible.

An underscore should be OK, at least I thought it was when I was still using NX (2+ years ago).

underscore is invalid as the first
character of an expression name.

 

[JohnRBaker]

Yes, that would be true, but as an embedded character, it should work.
