Javascript error..

[haku87]

Hi, my menu is using javascript to create. There has been an error. However, I cannot manage to find the bug..

Could anyone help?

It displays Object Required Line 137.

 

The website is http://www.bit-by-bit.edu.sg.

 

What is causing the problem. It was taken from dynamic drive. I did not change anything.

Well! the problem is with the line:-

 

document.getElementById(cid).style.display="block"

 

The issue is that the variable cid is having some value(say the value is xyz), then the html should contain an id corresponding to xyz like this:-

 

<span id="xyz"></span>

or

<div id="xyz"></div>

 

Try putting an alert before the line No. 136 and see what value the cid variable contains and whether that id is defined in the html
