FCC will not allow me to submit my technical documentation project

I have completed the first 3 projects in the wed development section, I have gone to submit the 4th one (technical documentation) but it is greyed out. I have completed the first 3 and they have all passed and can be viewed in my account.

Does anyone know what the problem is?

when you submit a link, the button should become clickable. if it doesn’t happen try reloading the page

also note that submitting a project doesn’t mean that it passes the tests, the projects are on an honor system, to see if they pass you need to use the provided test suite, and for feedback you can post in #project-feedback
