holy mother of pearl

ok, lets do this.

echo"<td><input type=text name=\"GP" .$i. "\" size=5></td>";

that line will read like this

<td><input type=text name="GP1" size=5></td>

so when it gets sent you will need to use this

$_REQUEST['GP1'];


so try this

PHP Code:
$result mysql_query
("INSERT INTO nbalive_daybyday 
(GP, Nickname, PTS, FGM, FGA) 
VALUES ('"
.$_REQUEST['GP$i']."' , '".$_REQUEST['Nickname$i']."' , '".$_REQUEST['PTS$i']."', '".$_REQUEST['FGM$i']."' , '".$_REQUEST['FGA$i']."')"); 
not sure if that will work.

I would look into using arrays in that form of yours.
