A while ago I was sent this solution to display a complex hash in a
select list.

Works like a champ, however in my web error log I'm getting warnings
about $abr not being previously initialized.  I've tried initializing it
by setting it to zero just prior to each select as such:

[- $abr = 0; -]<SELECT.....>.....

but I continue to receive this error.  I know it's just a warning but is
there anyway to get rid of this warning?

This warning comes from the end of the list. There must be one undefined
element, because that is the one that stops the list. So at the moment there
is no chance to get rid of it.
