Created attachment 200880 [details] "Manage Names" window with error message In order to avoid confusions I propose to adjust the error message in the "Manage Names" window in Calc. The error message could look like “Invalid name. Start with a letter, except c,C or r,R followed by a number. Use only letters, numbers and underscore.”
+ Adjust extended tip as well.
