asp.net mvc - In IE8, why am I getting a javascript error on my DocType line -

I get this error when running a webpage in Internet Explorer 8 (It is not certain that this is the case but when I Is loaded when it happens a jquery ui dialog)

When I click Yes, it brings IE8 JavaScript debugging tool, but what's odd is that it shows an error on the docktip line.

Can someone tell me Is trying to tell me what is IE and how can I debug it?

Update:

When I say in response to the people, I need to remove the blank line at the top, here my code is in my site. Any extra blank on any thing in the master file Not the line, so I do not know how to find this blank line when viewing the source in IE8.

  & lt;% @ import namespace = "domainmodel"% & gt; & Lt;% @ Import Namespace = "Mvc.Views.OrganisationalUnit"%> & Lt;% @ Master language = "C #" Inheritance = "System web.mvc.WeWMaster page    
 
 
 Try removing the white space at the top of the file (i.e. line 1). If that does not help, try to manually rewrite the string to make sure that there are no strange characters hidden there. Otherwise, this code looks valid for me.  
  Update:  
 Try removing the line breaks between your import statements:  
  & lt;% @ import namespace = "DomainModel"% & gt; & Lt;% @ import namespace = "Mvc.Views.OrganisationalUnit"% & gt; & Lt;% @ Master language = "C #" Inherits = "System.Web.Mvc.ViewMasterPage & lt; Mvc.ViewModels.BaseViewModel & gt;"% & Gt; & Lt ;!
