Why is there an error when integrating SIMGallery to replace JomSocial videos?

Hi Mike. I have enabled SIMGallery to Replace JomSocial's Videos Feature. When I click on the Videos link on the JomSocial profile page, I get a strange 1222 error. I copied the error message into the Misc Info below (too long for this text box).

This error occurs when I click on the mydomain.com/index.php/jomsocial/562-super-user/videos link.

The resulting page containing the error is:
mydomain.com/index.php/extensionspage/simgallery?view=album&layout=videos&uid=562

Please help!

Thanks,

Tim
