function PopWin(url,h,w) {
popupWin = window.open(url, 'popup', 'height=' + h + ',width=' + w + ',top=50,left=75')
}
// -->
</script>


<form action="todb.asp" target='popup' onSubmit="PopWin('about:blank',150,320);return true;">

        <input type="hidden" name="O" value="<%=Variabel1%>">
        <input type="hidden" name="T" value="<%=Variabel2%>">
        <input type="hidden" name="TH" value="<%=cOUTFile%>">

      <input type="submit" name="Submit" value="Submit">
</form>
