how to audit changes to a form

[muneermohd9690]

I have an access database for employees.certain users from manager level has access to this databse. I want to log any changes (add new,edit,delete) to the databse using vba code.the users will be using forms to do the edits. I have tried using the below code,but the problem is that the below code works only for a standalone form. My forms contain sub forms and navigation forms.
