Custom Badge

I have created a custom badge which I am trying to implement. This badge will need to be assigned and not earned.

Here is my code in my cidm.badge file:

[

    {

        // The title of the badge.

        "title"         : "Certificate in Digital Money Graduate",



        // The description of the badge

        "description"   : "You have successfully met the graduation criteria for a Certificate in Digital Money",



        // The steps needed to unlock this badge.

        "howto"         : "Enroll in, and sucessfully meet the graduation criteria for the Certificate in Digital Money ",



        // The alias of the badge.

        "alias"         : "cidm",



        // The extension for this badge.

        "extension"     : "com_easysocial",



        // The badge command.

        "command"       : "certificate.complete",



        // The default avatar for this rule. Relative to the site's document root a.k.a (JPATH_ROOT)

        "avatar"        : "media/com_easysocial/badges/cidm-grad.png",



        // When user creates a new discussion for 15 times.

        "frequency"     : 1

    }

]

For some reason everytime I try upload this using acheivements > install i get the following error:

0 SocialTableBadge::bind(*NULL*)

Im not sure what I have done wrong. Please assist.
