Please help me get my javascript popup window to show

Hi everyone,

I'm programming in VB.NET but I think that the coding for a javascript is the same.

I've been trying to pass a parameter to my popup window but I still can't do it.  I think that I am close because a browser window opens but it's a "Page cannot be found" page. 

Can you tell me what I'm doing wrong?  Do I need the javascript function and the inline javascript?  Here's my code:

I started with the tag

Here's my Hyperlink.  The part I'm having problums with is the NavagateUrl attribute. 

Why won't my popup window show?  Thanks for any help with this one.
