Correct handling _POST[] and implode. PHP5

Hi all, I have a form that has has an array of information. Mulitple checkboxes can be selected. Choose the colors: <input type="checkbox" name="Colors[]" value="green" checked="checked" /> Green <input type="checkbox" name="Colors[]" value="yellow" /> Yellow <input type="checkbox" name="Colors[]" value="red" /> Red <input type="checkbox" name="Colors[]" value="gray" /> Gray When processing the form.. echo $_POST['Colors'] . '<br />'; // outputs 'Array' if ( isset($_POST['Colors']) ) { $_POST['Colors'] = implode(', ', $_POST['Colors']); //Converts an array into a single string } echo "Colors you chose: {$_POST['Colors']}<br />"; I get the following error when using the implode function. Warning: implode() [function.implode]: Bad arguments What I doing wrong ?
