How to fix error: Object doesn't support this property or method

[Mark Drummond]

Hi guys, I've ran into a problem with IE and Javascript (Prototype framework to be specific). I'm developing a custom module to sit in a vle (Blackboard). Blackboard uses Prototype and Scriptaculous, so the module has been developed using the framework and module. The following line has been giving me grief.

this.carouselViewport = this.ArtGalleryelCarousel.down('.' + this.options.containerViewportClass);

I have tried changing the names of the variables just in case it is causing a conflict with another part of the script elsewhere but to no avail.

Any help on this matter would be greatly appreciated. Thanks.

Can you find out which part of the line it might be (by splitting over a number of lines, or debugging).

What does "this" refer to? Perhaps a link may help.
