Below I have a lot of Adding and values being created with PHP.

It all works fine! And it can be seen in action here: http://universitycompare.com

EXCEPT – the first set of PHP that has ‘$totalcost’ in it. I can’t seem to work out why my values created further below cannot be used to create a total.

Any opinions? 

<?php
$totalcost = $totalcost2 + $totalcost3; 
$totalcost2 = $li444 + $tuitionTotal;
$totalcost3 = $li4 + $li44;
?>

<!-- WORKING OUT TOTAL TCE -->

<p>
<b class="TCE">
<?php echo $totalcost; ?>
<?php echo array_sum($a); ?>
</b> 
</p>

<!-- END OF WORKING OUT TOTAL TCE -->

    Finally worked it out as it seems I didn’t know defining totals before was not possible, some strange reason I thought it would relay it back, lesson learned!

    <?php
// AVERAGE DRINK COSTS 
$li2 = get_field('average_drinks_spenditure_per_night');
$li3 = ($li2 * 28) * 2.1;
$li4 = $li3 * 3;

// HOUSING COSTS 
$li22 = (get_field('average_housing_costs_per_week') * 4 );
$li33 = $li22 * 12;
$li44 = $li33 * 3;

// SHOPPING COSTS 
$li222 = (get_field('average_shopping_trip_price') * 2.25 );
$li333 = $li222 * 12;
$li444 = $li333 * 3;

// TUITION FEES 
$tuitionClass = (get_field('tuition_fees') /28 );
$tuitionTotal = (get_field('tuition_fees') * 3 );

// PHP TCE 
$totalcost2 = $li444 + $tuitionTotal;
$totalcost3 = $li4 + $li44;
$totalcost = $totalcost2 + $totalcost3; 
?>

    This is what I used in the end and just put that before any of the values needed to echo’d.
