PHP:

document.getElementById aint working in Firefox/Safari. Can somebody please help.

Additional Updates:
Its working in IE though

 

How are you passing the id?

btw, the <script> tag should look like this: <script type="application/javascript">

passing thru asp.net

 

The usual cause of this problem is when the parameter passed is actually a name attribute instead of an id. Since you haven't shown the element, it's not possible to tell.
