Failed to find block 'ecard button'

[greattastic]

I just set up a new theme for my site, and I'm getting this error whenever I try to go to any individual picture's page

Template error
Failed to find block 'ecard_button'(#(<!-- BEGIN ecard_button -->)(.*?)(<!-- END ecard_button -->)#s) in :

                </td>
        </tr>

Can anyone help me figure out what's missing and how I can fix it?

Thanks in advance!
