Column A contains a list of strings, under the heading "thing". Next
to each string, Column B contains blanks or an "x", with a date as a
heading. In another worksheet, I want to create a list of all the
values in Column A which have an "x" next to them in Column B. How can
I do this?

View the following in fixed-with font.

For example, if this is my first table:

A B C
thing 1/28/2006 1/29/2006
rock x
scissors x
frog x x
flipper
grumpy x
doctor x
notebook x
power x x

I want my second table to look like:

A B
1/28/2006 1/29/2006
rock scissors
frog frog
doctor grumpy
power notebook
power

And so on, for each day.

And for mondo extra bonus points, propose a way to do this in reverse.
That is, to put an "x" under the appropriate date column in the same
row (in table 1) as the things listed in table 2.

Much thanks-
Peter Keller
