Error when trying to add listing

Getting following error when trying to add / submit a listing

Warning: in_array() [function.in-array]: Wrong datatype for second argument in /home/namibiac/public_html/addlisting.php on line 175

Have checked the problem lines, all are as follows:
if (in_array(1,$re s)) {
if (in_array(2,$re s)) {
if (in_array(3,$re s)) {
if (in_array(4,$re s)) {
if (in_array(5,$re s)) {
if (in_array(6,$re s)) {
if (in_array(7,$re s)) {

Thanks

Can we see the code please?

The second argument to in_array() needs to be an array.
