can't craft Advanced solar helmet

  • Hi, I'm using advanced solar panel 3.5.1 mod with IC2 exp 2.2.785 and I'm trying to craft advanced solar helmet, hybrid solar helmet, and ultimate solar helmet in advanced solar panel mod. I can see an appropriate recipe for those items, but, I can't craft those items.. I don't know why.. I have all items in recipe, but when i put on those recipe items on crafting table, resulting item which is advanced solar helmet doesn't come out...
    can you tell me why? and how can I fix this?
