I have this form on page test.php (frame"below")
<form method="post" target="main" action="test2.php">
<input type="submit" value=" button " ></form>
When someone click the button the form open test2.php on frame "main" .
I would that then when someone click the button the frame "below" (where is the web form) should open a new page for example test3.php
