It is what you're looking for, you just need to think it through a little.
instead of
> $chk_$row["field"]
try
$foo = "chk_" . $row["field"];
$bar = $$foo;
or if you're trying to do something else, you may need
$foo = "chk_" . $row;
$bar = ($$foo)["field"];
as I'm not sure which order of execution you want to happen on that
line, since it's not valid :)
