[Plugin: NextGEN Gallery] how to make a custom gallery sub page

Hi I would like to make a custom gallery sub page.

I have a ‘main gallery’ page with a list of album thumbnails. I also have a ‘gallery-detailed’ page. When the selected album thumbnail is clicked on the ‘main gallery’ page it goes to the ‘gallery-detailed’ page.

I have deactivated the “gallery page link” option in the NextGen Gallery dashboard and linked up all the galleries which I created to the ‘gallery-detailed’ page, however on my ‘gallery-detailed’ php page I don’t know how to show the images within whichever gallery the user clicks on.

If I activate the ‘gallery page link’ option I can make it work but I want to customize my ‘gallery-detailed’ page so it is different from the ‘main gallery’ page therefore I can’t have that option selected.

I use this
<?php echo apply_filters(‘the_content’, ‘[nggallery id=x]’);?>
but an error message comes up saying “Gallery not found”

if I use [nggallery id=1] or place any id numbers it works but off course it will show the album of the id number and this is not ideal because my galleries has to be created dynamically.

Please help me.

Thanks in advance.
