There's an extra space between the opening "(" and the opening "$[", so
the result is space-zero, which is not the same thing as zero.  Any
string
that is not exactly "0" (or the empty string), such as "foo", " ", or "
0" is
true.

I did wonder where the extra spaces were coming from, but I thought that
was where the quotes were supposed to come into play...  Well that got
it working so thanks guys..
