Link in JS

I have a link on a page containing frames. The link is OK, except when I have opened a new window. What could be wrong? Do I have to activate the window with the frames or...?

Link code:

Code:

---

<a href="pipedim.asp?pageID=<%=pageID%>" target="venstre" onclick="pipedim();" style="font-size: 12pt">This is the link</a>

---

function:

Code:

---

function pipedim() {
  window.parent.frames("right").location = "blank.htm";       
  parent.frames[0].navform.dim.disabled=false;
  return;
}

---

An error occurs if I hit "This is the link" after activating a new window with this form:

Code:

---

<form name=pipe_res method="post" action="print.asp?pageID=<%=pageID%>" target="_blank">

---

The error occurs happen in the right frame, left is OK

What error are you getting?

A simple error saying that the ressource is not allowedt. This is the HTTP 405 error.
