Wrong code or not?

So I saw a code from a YouTuber, and the code happens to be “CUSTOM”, and it was supposed to give me a 2x earning bonus. However, I think I just put Custom or custom, and it now says I only have a 1x earning bonus. Would the capitalization change anything? And is there anyway I can change the code to the right thing to get the 2x earning bonus?
