I am trying to use the DynTabFrame. I have created a DynaTab with the following 
$dynatab_name = 'SNG';
dynatab_frame_child($tab_Tabbed, \$tabbed_frame{$dynatab_name}, $dynat
+ab_caption, $dynatab_title, $dynatab_image, $dynatab_colour , $dynata
+b_raised_colour);

$tab_tabbed has been created as a DynaTabFrame

This is the code for the dyantab_frame_child 

sub     dynatab_frame_child($$$$$$$) {
my ($tab_parent, $ref_child, $dynatab_caption, $dynatab_title, $dynata
+b_image, $dynatab_colour ,$dynatab_raised_colour) = @_;
$$ref_child = $tab_parent->add(
                -caption => $dynatab_caption, 
                -label    => $dynatab_title,
                -tabtip => "Tip for tabno",
            )
            ->pack()
            ;
}

The following is a sub where I am trying to hide this tab frame using the sub hid_tab called from a button 
sub hide_tab() {

my ($hidden_value, $dynatab_name);

$dynatab_name = 'SNG';

print "\n[hide_tab] entered\n";

$hidden_value = $tabbed_frame{$dynatab_name}->cget(-hidden);

print "\n[hide_tab] for $dynatab_name - $hidden_value <$hidden_value>\
+n";

if(length($hidden_value) == 0) {

    print "\n[hide_tab] hiding $dynatab_name - $hidden_value <$hidden_
+value>\n";

    $tabbed_frame{$dynatab_name}->configure(-hidden => 1);
}
}

This is the error I get in the hide_tab sub 
[hide_tab] hiding SNG -  <>
Tk::Error: Can't set -hidden to `1' for Tk::Frame=HASH(0x20f90157e48):
+ unknown option "-hidden" at C:.....

What am I doing wrong?

The pod for DynaTab has:

-hidden
When set to a true value, causes the resulting tab to be hidden from view; can later be set to a false value to force the tab to be visible again.
