Hello Monks

I am attempting to figure out how to select a new cell and deselect the previously selected cell when the new cell is selected and I am just not sure how to do it

I am testing with code I found on Active State's site

use Tk;
use Tk::Table;

my $mw = MainWindow->new;
my $table = $mw->Table->pack;

my $r;
foreach $r (0..5)
 {
  my $c;
  foreach $c (0..5)
   {
    $table->put($r,$c,"$r,$c");             
    $table->get($r,$c)->bindtags([$table]); # messy
   }
 }

$table->bind('<1>',
          sub {
           my ($w) = @_;
           my ($row,$col) = $table->Posn($w);
           print "row=$row, col=$col\n";
           $w->configure(-background=>'grey');
          });

MainLoop;

When this code is run on each cell that is clicked on (selected), the background is changed to grey. I would like to have it grey the new cell that is selected and change the previous selected cell back to white, ultimately deselecting the previous cell. The goal is to only have one cell selected at a time, not multiples

I don't seem to be able to come up with the necessary logic to do this. I tried adding a variable to save the row/column. Anyway, I would appreciate any words of wisdom, suggestions/examples etc, that you may have

Thank You
