Specifying the target window

[joey o.]

I'm using onclick to call this VB sub from a frame to populate my frame:

Sub Run2Locs
Window.open "HomePage.asp?hp=prod target=Forms"
Window.open "Menu.asp?hp=hd target=Buttons"
End Sub

This doesn't work . It ignores "target" and opens up independent windows. Does anyone know how I can specify the target using VBScript?
