Invalid arguement supplied for foreach()

When filling out this form, you have to select the “Drop” Order Type and submit to see this error:
E_WARNING Invalid argument supplied for foreach() – /…/…/…/patrickforms.com/wp-content/plugins/gravity-forms-list-field-select-drop-down/gravity-forms-list-field-drop-down.php:108

And this is the code on and around line 108 of the plugin:

foreach ( $list_values as $key => $value ) { // get each row
	$isDropDown = $field->itsg_list_field_drop_down;
	$isDropDownEnableChoiceValue = $field->isDropDownEnableChoiceValue;
	$choices = $field->isDropDownChoices;
	if ( $isDropDown && $isDropDownEnableChoiceValue ) {
		foreach ( $choices as $ch ) { // get each row
			if ( $value == $ch['value'] ) {
				$list_values[ $key ] = $ch['text'];
			}
		}
	}
}
$submit_value = $list_values; // add row to submit value array
