Ravelry Question?

[kellybigeyes]

I didn't know where else to post this and the question "thing" on ravelry looked very hard. I am very new adding things to ravelry. I just began taking pictures of my stash, projects, etc. I added my entire stash and now I am going back and added my projects. When I add a new project, I can't seem to add the yarn that I used from my stash. When I click "use stash yarn"... the box pops up with everything listed, but I can't click on any of it to actually add it. I hope this all makes sense. Can someone please help?
