Kevin is correct.  (Whether he "peeked" or not, who knows :)

Seriously, this is an "operator precedence" problem, as Kev points out. 
The "better" that he mentions below is really the best for clarity but
no more "right" than the first "fix" he recommends in using the
parenthesis around the weaker assignment operator.  Of course, in his
"better" approach, it isn't as easy to "fool" people on test questions
