You can nest [loop] tags, as long as you use a different "prefix" and
"list_prefix" for each [loop].
If you find yourself nesting [loop] tags then you may find it more
efficient to create a single SQL statement that selects everything
in one hit.

You can correct that loop a number of ways. Here are a couple
of them:
1) Add "code" to the rf (rf=code,tier,quantity,discount).
[FLY-data] uses the [FLY-code] as the key, and [FLY-code]
is the first column in the resultset.
2) Replace your [FLY-data tiers whatever] tags with
[FLY-param whatever]. This is the more efficient way of
doing it; Why force another data lookup when you already
have the results?

Yes - but not an Interchange bug. :-)
