iframe module warning

Hi,

I´m trying to create a content type including a "wrapper" like joomla. I installed the iframe module, and when I add the new field in a content type (field type IFrame) I have the following warning and the field is not created:

user warning: Unknown column 'locked' in 'field list' query: INSERT INTO content_node_field (field_name, type, global_settings, required, multiple, db_storage, module, db_columns, active, locked) VALUES ('field_iframe2', 'iframe', 'a:7:{s:10:\"attributes\";s:0:\"\";s:7:\"display\";s:0:\"\";s:3:\"url\";s:0:\"\";s:5:\"title\";s:0:\"\";s:11:\"title_value\";s:0:\"\";s:6:\"target\";s:0:\"\";s:13:\"enable_tokens\";s:0:\"\";}', 0, 0, 1, 'iframe', 'a:4:{s:3:\"url\";a:4:{s:4:\"type\";s:7:\"varchar\";s:6:\"length\";i:255;s:8:\"not null\";b:0;s:8:\"sortable\";b:1;}s:5:\"title\";a:4:{s:4:\"type\";s:7:\"varchar\";s:6:\"length\";i:255;s:8:\"not null\";b:0;s:8:\"sortable\";b:1;}s:6:\"target\";a:4:{s:4:\"type\";s:7:\"varchar\";s:6:\"length\";i:255;s:8:\"not null\";b:0;s:8:\"sortable\";b:1;}s:10:\"attributes\";a:3:{s:4:\"type\";s:4:\"text\";s:4:\"size\";s:6:\"medium\";s:8:\"not null\";b:0;}}', 1, 0) in /var/www/oeg4/includes/common.inc on line 3308.

How can I do a wrapper??

Thanks!
