I’m trying to display the sum of entries in a field based on values in another field/s.
I’ve using the details stack and richtext field stack to get it to select the correct data using the ‘Where’ statement and using the code
%field(inventory_value)%
it correctly displayed the first entry that meets the criteria (it worked)

To get the sum working i tried %sum(inventory_value)% but that didn’t work, any ideas what would be the correct code?
Am I going about this the right way? with the details/richtext field stack?

Tried taking a different track by inserting html/php code stack
I can get it to connect to the database using the code below
<?php
$dbhost = 'localhost:3306';
$dbuser = '*******';
$dbpass = '*********' ;
$conn = mysql_connect($dbhost, $dbuser, $dbpass);
if (! $conn )
{
die('could not connect: ' . mysql_error());
}
echo 'Connected successfully';
mysql_close($conn);
?>
This works and displays the text ‘Connected successfully’
but as i have next to no php knowledge i tried the code
<?php
$dbhost = 'localhost:3306';
$dbuser = '********';
$dbpass = '*********' ;
$conn = mysql_connect($dbhost, $dbuser, $dbpass);
if (! $conn )
{
die('could not connect: ' . mysql_error());
}
echo 'Connected successfully';
mysql> SELECT SUM(inventory_value)
-> FROM inventory WHERE student = session(userid) AND sub_category = "safety"
mysql_close($conn);
?>
but it crashed, being php I hope this would be an easy answer fro someone now
