Error question about Superclean -but functioning properly

Hi guys,

I am new to Joomla and RS Gallery so bear with me... I am a Grandma now so I have the right to be slow on my computer. Roll Eyes

I sort of made a few changes with my Joomla template (Joomla Art Pariiti) so I could display a photo gallery. I did not like the way the gallery was set up because visitors have to click the gallery, then click the thumbnail, then would finally arrive at their photo. I built my own gallery where visitors click an image and are taken directly to the thumbnails. I installed Superclean so the only thing people have to do is click the image. I really like the Superclean template. It is exactly what I wanted my photos to do.

Everything is working but does show errors at the bottom of the browsers. I am not sure how to fix them, or if they are fixable. I have probably messed something up along the way I'm sure. Undecided

Below are the errors that Firefox is showing me. If someone has time, can you please tell me if these errors might be fixable?

Lightbox.init.bind is not a function
window.addEvent('domready', Lightbox.init.bind(Lightbox));
slimbox.js (line 218)
overlib is not defined
return overlib(html, FULLHTML);
