It only shows you the first error.
Then I totally don't understand this at all. Why can't I cast it? I need a total of 27 skill levels? What skill levels?
But ability to cast a spell, regardless of current Energy/Concentration, is firstly dependent on the sum of Base Skill Level and Intent Skill Level, which in this case is (Mind 4 + Perceive 3) => 7 max Power Level spell using Mind+Perceive that you can cast.
I've read through the site several times, and there's nothing on the site that I have found that would explain that.
