PHP MySQL Queries

P: n/a
Is this possible?

I have a form which asks the user to input the result of a soccer
match.

I want to then use a choice of three sets of queries (Home Win, Away
Win, Draw) to update two tables, Matches (the master list of all
matches and there results) and Teams (a list of all teams with total
numbers of matches played, won, lost drawn etc?)

So far I have managed to update the table matches but nothing happens
to teams. The page appears to run correctly so I am at a loss to
understand what is happening.

PHP AS IT STANDS

<?

// scoreinput.php - input a match score when match selected from list
?>
<html>
<head>
<basefont face="Verdana">
</head>

<body>

<!-- standard page header begins -->
