I've got another error that I can't seem to nail down and it doesn't seem to reference a line of code that I can see.
Parse error: syntax error, unexpected $end in /home/a7232973/public_html/phptroubleshooting.php on line 29
<?php
//adder.php
if (isset($_POST['num1']))
{
$num1 = $_POST['num1'];
$num2 = $_POST['num2'];
$myTotal -= $num1 + $num2;
print "<h2 align=center>You added <font color=blue>". $num1 ."</font> and ";
print "<font color=blue>" . $num2 . "</font> and the answer is <font color=red>" . $myTotal ."</font>!";
unset($_POST['num1']);
unset($_POST['num2']);
print "<br /><a href=" . $_SERVER['PHP_SELF'] . ">Reset page</a>";
