Yet another IE 'Object expected' error with no information

Question

Hey, I have been pulling my hair out with this error I am having on this site.

I am getting the dreaded Object expected error on line 1, character 21 in

Answer 1

We fixed the "Object expected" error in IE, so to answer the question in your comments:

The problem is in your HTML.

You have this HTML, once for each tab:

    
Introduction

The problem is that you're specifying two elements with id='introduction'.

For various reasons, you should not do that:

• It's causing validation errors.

  Line 37, Column 27: Duplicate ID introduction.
  Line 36, Column 39: The first occurrence of ID introduction was here.

• It's breaking your tabs in IE7.
• There are also other reasons, but they aren't important here.

If I change it to (for example):

    
Introduction

(remember to change all four instances in the same way)

And if I change your JS to this (for example), it works:

// Show selected
Spark('.' + currentTab)
