I have a spiffy drop-down (with the box and arrow) that, when different
selections are chosen, modifies a chart to display different values. I cannot
find a way to lock (and protect) the drop-down (so it can't be moved) and the
chart (so that people - including myself - can't mess with the source data
and such), but still be able to use the drop-down and watch the chart change
to the new values.

I know this is possible, as I have a worksheet that does it, but I can't for
the life of me remember what I did.

Thanks for any help
