    What is wrong with this statement in an 'if' block?

    if ((scalar1 == 0) || (scalar2 == 0) || (scalar3) == 0 || (scalar4 == 0))

    I basically want to say: if any of the four scalars are individually equal to zero, then execute the subsequent statements.

    I spent a good ten minutes looking at the question while trying to figure out why the code wouldn't work. Then I noticed the brackets!
