[horde] IMP Quota display

[Pine A]

I am trying to display quota on sidebar in imp.

For this I am following code in imp/lib/dynamic/mailbox.php

$sidebar->subinfo = $imp_imap->config->quota;

For displaying in sidebar we are writing following code in
templates/sidebar/sidebar.html.php

<?php echo $sidebar->subinfo ?>

but not able to see anything there, is there anyway to get this working or
any pointers.

Thanks in advance

Regards,
