A validation issue

Well, it seems that I have a validation problem with an application I made. It's an article publisher. If I want to modify a record, I can delete an entire field and go along with it empty in the db in spite of the jscript validation I have on the page. But if I come back to the same record, and want to make another change, well it suddenly discover the empty field and woould not let me go along and insert it empty. To better understand what is all about, check it here, and try to Modify an article. It seems that the records "inside" HTMLArea, does not get verifyed by my validation function, but the rest of them do.

Sorry to come back so late, but it seems that some notifications do not reach me.

The problem is that you can delete the content and then go along and insert the empty field in the db, despite the validation i put against it. But if you came back again and edit the same record, it suddenly discover the empty field and prompts you to fill it in.
