Hi,
I have this:

and:
[CODE]<html>
<head>
<title>Form</title>
</head>
<body>
<form method=”get” action=”spiral.php”>
<input type=”text” name=”use” />
<input type=”text” name=”r1″ />
<input type=”text” name=”r2″ />
<input type=”text” name=”r3″ />
<input type=”text” name=”r4″ />
<input type=”text” name=”r5″ />
<input type=”text” name=”r6″ />
<input type=”text” name=”r7″ />
<input type=”text” name=”r8″ />
<input type=”text” name=”r9″ />
<input type=”submit” />
</form>
</body>
</html>
If use=”yes” then the values r1 to r9 should equal what they’re specified in the form, or if they’re blank, a random number between 0 and 255. If use=no then r1-9 are all random.
Thanks,
