I am writing a technical documentation where I have to explain that you can name variables like "Name", "email", and "AGE". However, they cannot define another variable called "name" if "Name" is already defined.
My error message, in that case, reads like the following:
"Name" must be used in the same letter case.
The alternative could be something like the following:
"Name" must be used in the same capitalization.
What I am effectively trying do is to force case-insensitivity in a system that allows case-sensitivity. And I am not happy with either style of the error messages. case, for instance, might confuse some people. capitalization might sound weird if the original variable was itself called "name".
Is there a better/recommended way to write my error messages?
Thank you very much for your help!
