Newbye question

I installed php 4.2.1 on windows XP using the PHP 4.2.1 installer [897Kb] - 13 May 2002 Apparently php is working since the classic hello word from php is running, but I have some problems with variables I have the following php code, who runs perfectly on my isp, but give a message error on my machine who use windows xp the message are Notice: Undefined variable: texto in d:\inetpub\wwwroot\souio\php\teste03.php on line 5 I'm sure the code is correct because they run on my ISP (W2000) without any problem what is wrong witch my installation? The code are <html> <head><title>Learning PHP</title></head> <body> <?php if ($texto != "") echo "You typed \"$texto\"<br><br>"; ?> <form method=post action="<? echo $PATH_INFO; ?>"> <input type="text" name="texto" value="" size=10> <br> <input type="submit" name="sub" value="Enviar!"> </form> </body> </html>
