Henrik,
I think your problem is jsimply that you are not getting variable substitution
of $HTTP_GET_VARS["whatever"] inside double quotes.
print "whatever is $HTTP_GET_VARS["whatever"]";
is not safe.
You need
print "whatever is {$HTTP_GET_VARS["whatever"]}";
or, (IMHO better),
print 'whatever is '.$HTTP_GET_VARS["whatever"];
The fact that you are actually evaluating an assignment is I think irrelevant, it's
just the
variable substitution that's failing. See the variable parsing section of
http://www.php.net/manual/en/language.types.string.php
