Add the target tag target="_top"

Hi can someone help me with this one? I have a redirection page for flash but I need to add the target tag target="_top" to the script. How do I do this?

<SCRIPT LANGUAGE=VBScript>

<!--

on error resume next

var GotFlash

GotFlash = IsObject(CreateObject("ShockwaveFlash.ShockwaveFlash.3"))

If GotFlash = True Then

Window.Location= "http://web.ukonline.co.uk/lymt/mainFrameset.htm"

End If

// -->

</SCRIPT>
