I'm doing a refresher on this course and I am stuck once again.

What am I missing?

Thanks!

palindromic_primes.php
```<?php

function mimic_array_sum(\$array){
\$sum = 0;
foreach (\$array as \$element){
\$sum = \$sum + \$element;

}
return \$sum;
};

\$sum = mimic_array_sum(\$palindromic_primes);
echo \$sum;

\$palindromic_primes = array(11, 757, 16361);

?>
``` Juliette,

You just need to move your \$sum variable and the echo statement below the \$palindromic_primes array, and you will be good to go!

```<?php
// all you need to do is move your \$sum variable and its echo statement below the \$palindromic_primes array, like so!

function mimic_array_sum(\$array){
\$sum = 0;
foreach (\$array as \$element){
\$sum = \$sum + \$element;
}
return \$sum;
};

\$palindromic_primes = array(11, 757, 16361);

\$sum = mimic_array_sum(\$palindromic_primes);
echo \$sum;
```

Everything else with your code is fine :)
