The first thing you need to know is that what you type into the web interface for the CSQ name is King.
The next thing you need to know is that in a script, there is no validation that you typed the CSQ name correctly, so my advice to you, is to always use Copy/Paste from Web to Script when dealing with CSQ names.
The last thing you need to know is that a String variable name has nothing to do with its value, in that, your CSQ variable name could be banana, but the value could be "apple." It's the value which matters, not the name. However, if you have named your variable the same as it's value, you've defeated the point of variables in the first place, and you should pick a new name for your variable, such as simply: csq.
Bonus: The order you change the name in: e.g., script first, web second, or web first, script second, doesn't matter, as it will break in both cases, until you change both.
Bonus Bonus: Your reporting will now contain both names for a really long time (a year or more), and you cannot purge or convert the old name from reporting.
