Database error with "Files"

Getting REALLY frustrated with this platform.  I decided that there should be some pages that I can monetize.  There were failures on some plugins so I had to follow the gopher down the hole that led to installing the "files" plugin.  Now my menu is showing a new link and I get the following error when trying to install the module "files"

Installation of: Files Failed

INSERT INTO `sys_menu_top` (`Parent`, `Name`, `Caption`, `Link`, `Order`, `Visible`, `Target`, `Onclick`, `Check`, `Editable`, `Deletable`, `Active`, `Type`, `Picture`, `BQuickLink`, `Statistics`) VALUES(4, 'Files', '_bx_files_menu_profile', 'modules/?r=files/albums/my/main/|modules/?r=files/albums/my/add/|modules/?r=files/albums/my/manage/|modules/?r=files/albums/my/disapproved/', @iCatProfileOrder, 'memb', '', '', '', 1, 1, 1, 'custom', '', 0, '');

I yanked the "files" menu from the site so it would not show, but still getting the error when trying to install the module.

Search that table for any entries for the Files module, delete them, then clear Dolphin's cache. Re-try the installation.

These problems only occur on sites where the menu has been adjusted by custom templates etc. Modify the file shown below and re-upload to your server then the install should be fine.

In modules\boonex\files\install\sql\install.sql

Find two occurences of :

     @iCatProfileOrder,

Replace both occurences with :

    IFNULL(@iCatProfileOrder, 1),

Modzzz, I followed old instructions with the following and it seems to have installed correctly.  Can you explain the difference between your suggestion and this one please?

In modules/boonex/files/install/sql/install.sql


Find (2 occurrences) :

, @iCatProfileOrder,

Replace with :

, '@iCatProfileOrder',

Just different ways of accomplishing the same thing.
