Why are some .html pages green and unavailable to be linked?

I’m using glitch for a class and we’ve been assigned to make a ‘choose your own adventure’ website in which each page has links which take us to other pages on the site. So far I’ve been successful, but now I’m having trouble linking my 13th (and onward) pages. Is there a page limit? html title for the 13th page is green (while the others are purple) and it does not allow me to link it. Help!

could you send your project name? it could probably be something wrong with your code.

Yes, the project name is day-dream . Thanks! I’m new to coding.

nevermind, i notice what you are meaning. could you try deleting and re-adding the file?
jenn could maybe help you because i don’t know about this that much

edit again: deleting and re-adding the file fixes the problem
