[RESOLVED] Javascript: Object Expected PART 2

[niclipse]

As mentioned in my previous post with the same title, I am trying to move all of my javascript to external files. This hasn't been so easy. The last script was made to be written internally and I just rearranged it so it could be read as an external file. In doing so, I didn't realize that some of the things i wrote were case sensitive.

My next issue won't be so simple, because in this case, I am actuall take the internal script which is layed out just fine, and moving it to an external file. When I do this, I get the same non descript error "Object Expected"

Here is the document at hand:
