Need help setting up an 8 way roll dodge blend space

Moving on, I thought about trying to make holding the the right face button (B Key for Xbox 360 pad) for 1 or so seconds trigger prone. But for some reason I can’t figure it out. The only thing I have saw it do is instantly go prone like my 1 second conditions for the branch do nothing. Any help about what I’m doing wrong here is much appreciated thanks!
