Validate Form Before Navigating To Next Record

Hi

I was wondering if anybody could help with this. I have searched through this forum and there doesnt seem to be an answer to this.

I have a form that i would like to validate. At present i have put the data validation on the save button which triggers a script that checks to see if certain boxes have been filled in on the form. I can only get this to work be attaching it to the onclick event on a save button, however, what i really want is to be able to ditch the save button (since access writes to the DB as it goes along) and have this script triggered whenever the user tries to navigate to either a new record/ another existing record or close the form

I tried putting this on the beforer update event, but this does not work, additionally tried doing before update event with the code inside an if me.form.dirty = true statement
this did not work either, has anybody got any suggestions

Please see my code below

Thanks

Marcus
