frame problem

[Anon]

Hi!
I have a web page composed by 2 frames.

The main page is main.php, the upper frame is called "frame_up", the other is called "frame_down"

In the upper frame i have this code:
<a href="main.php?foo=10" target="frame_down">Link</a>

The problem is that the variable foo is not passed to the page in "frame_down".
In the "frame_down" i have a piece of code that print the variable foo, with echo $foo.
This, returns nothing.

Help me! Thanks a lot

Resolved!
In the upper frame, put this:
<a href="main.php?pippo=$quantity" target="_parent">, while in the main.php, set the frame as follow:

<frameset ....

<frame name="frame_down" src="main.php?bar=<?php echo $foo; ?>">

</frameset>

Finally, in frame_down put
echo $bar, and it works! :-)
