Cool, but there is one problem. It only works sometimes. For instance, I placed the HTML code on my desktop and saved the text as .htm-

Open the file in IE and click to accept blocked content. Then I entered a number. Sometimes it works and goes to the document.location url.. but sometimes it just goes to:
ile:///C:/Documents%20and%20Settings/bomgardd/Desktop/pr.htm?number=32155

working:
ttp://server/page/Main.htm?ServerFilter="PRNumber=98656"
