Hi all i got html page that has few frames in it. in one of the frames(refresh.php) i have the follow script :

<script language="JavaScript">
if (self.parent.frames.length != 0)
<frameset framespacing="0" border="0" cols="115,*" frameborder="0">
  <frame name="menu" src="./menu.php?username=<?php echo $Name?>" >
  <frameset rows="1,75,*" >
  	 <frame name="CHECK" scrolling="no" noresize src="./refresh.php">
    <frame name="adframe" scrolling="no" noresize src="./adframe.php">
    <frame name="main" scrolling="auto" src="./main.php?username=<?php echo $Name?>&Timestamp=<?php echo date("g:i A l, F j Y.");?>" >
which opens go.php page in whole window but i wonder how i can changes its target so it opens it with in my main frame rather then the whole page.I be happy if an expert show me how.Thanks
