Multiple record update as plug-in

I'm trying to create a multiple record update form as a plug-in on an administrator dashboard. The idea is that the administrator can update the authorised state of multiple organisations that have registered on the website. I have followed the tutorial on this from your site. I want to use the Update multiple records as a plug-in because I might need to use it on different pages of the admin system I'm building.

When I click the update button on my admin dashboard I get an error message stating I don't have permission to access the plug-ins directory. I think the error is occuring because the plug-in file is in a plugins directory and actual admin-dashboard.php file that it's plugging in to is in a separate admin directory. However, I don't know how to correct this error as I can't see anything in the WA generated code.

I've attached both files in a zip for reference any help is greatly appreciated.

I'll need to troubleshoot directly, see the private message section.

I've left the details you asked for in the private section

the problem was the form action:

<form action="" method="post" enctype="application/x-www-form-urlencoded" name="frmOrganisations" id="frmOrganisations">

in a plugin page, the action should not be left blank, it should use the PHP Self variable to post to the plugin page:

<form action="<?php echo (htmlentities($_SERVER["PHP_SELF"], ENT_QUOTES)); ?>" method="post" enctype="application/x-www-form-urlencoded" name="frmOrganisations" id="frmOrganisations">


you had also left the checked value for the checkbox blank.

i corrected that by changing the checked value to 1.

Thank you for your assistance. Much appreciated.
