[rules-users] What's wrong with the connectives?

[Edson Tirelli]

    Ouch.

    Start by removing all those null checks, since things like:

age > 17

    Will always return false if the age field is null, so the null check is
redundant.
    Also, replace top level && by ",", since this will make your constraint
groups clear.
    Then finally, make sure your ()-pairs are all fine and it should work.

    Just taking a quick look here I see an extra ")" here:

bodyFat > 0.31)
