Thanks for the clarification. I suspected something of this sort was the case.
Whenever I don't remember what the operator precedence is, I always add a few
parentheses. I still often tend to do something like:
{{{
if (($age > 18) && ($name eq "Catherine"))
}}}
(I.e: put parentheses around the clauses of if statements, even though they
are not needed or I could use the ultra-low-precedence "and"/"or"/etc.)
