Can't find the fault in this code

[Dwinna]

Greetings,

I've registered to this board specifically for this problem, though I'm beginning to suspect that I'll be here MUCH more often.

Recently I've tried to add a Lightbox script to an already existing page that already had a javascript feature in it. Now I know that there's no limit to the number of scripts you can run simultaneously, but when I added the lightbox feauture, my compiler gave me the following error:

$ is not defined
this.elements = $(this.options.thumb...lements(this.options.itemsSelector);

This line of code was part of the original source code of the page, and hadn't been a problem before I added the Lightbox code. Why is $ undefined all of a sudden and where can I find a solution for this? Could someone point me in the right direction here? I'm not exactly a novice(yet) when it comes to Javascript and this project was due yesterday.
I'd appreciate it if you guys could help me.

That's not valid JavaScript, so there's a problem with the original source-code. Where did you get that from?

Thanks Fang, I'm trying out your solution right now.

@Declan: The line of code I posted is from the .js file of the original index.html page (it was a template).

But did you take the line from the error console? It's obviously not complete with the ellipsis in the middle.

Yes I did actually.

There seem to be no more conflict errors after trying and testing the methods described in Fang's link, but now the page isn't supposed to do what I originally intended it to do, which is have a javascript clickable image sidescroller, and the images themselves to pop-up in a lightbox. Now you can scroll through the images, but onClick the image just opens in a new browser window.

Could I be in over my head here?

The sidescroller is overwriting the lightbox event handler.
Perhaps another lightbox has both functions.
