PHP Code:
<?php
$connection
=mysql_connect ("localhost""spike""9sj7En4");
if (!
$connection)
{
die  (
'Could not Connect: 'mysql_error());
}
mysql_select_db ("My_DB"$connection) or die (mysql_error());
if(!(isset(
$_POST['submit_button']))){
// they did not click the button
$result mysql_query ("SELECT * FROM Expenses") or die (mysql_error());
echo 
"<table  border='2'>
<tr>
<th>Category</th>
<th>Date</th>
<th>Dollar Amount</th>
</tr>"
;
while (
$rowmysql_fetch_array ($result))
{
echo  
"<tr>";
echo  
"<td>" .$row ['Category'] ."</td>" ;
echo  
"<td>" .$row ['Date']  ."  </td>";
echo  
"<td>" .$row ['Dollar Amount'] . "  </td>";
echo  
"</tr>";
}
echo 
"</table>";
}else{
// the form was submitted
// retrieve all the values from the form here
}
mysql_close ($connection);
?>
Now, you only have to make sure the button name in the form
is 'submit_button' for example :

HTML Code:
<form action="" method="post">
......
<input type="submit" value="GO" name="submit_button" />
</form>
Considering your new to PHP, I want to let you know using single-quotes instead
of double-quotes speeds up your script.

Regards.
