Someone can check this join function?

What's wrong with:

$inputorgaan = join(", ", $orgaan);

It's in a processing script to put a form into a db.

The following error:
Warning: Bad arguments to join() in /homes/i/indis/www/mysql/invoerscript_product.php3 on line 8

This creates the $orgaan for the processing script (deleted all the options):

<select name="orgaan" size="5" multiple>
<option>Organen:</option>
<option>OPTIONS</option>
</select>

What can be the problem?

Hmmm...

It gives a warning about your arguments to join(). The join() accepts two arguments, we can check if there is something wrong with it. The first argument to join() is a string and we can see that you do indeed have a string. The second argument to join() is an array. From the code snippet, I don't know if $orgaan is indeed an array. If it is indeed an array, is it empty?

I hope this helps.
