I just noticed the Contador field is text type. Count is a number value.
You want to show just the count or the full records from audit table?
To show just the count, can use DCount function in a textbox on form that will count the audit records. If you want to view the records, use code in some event to open a form filtered to the related records. You want the form locked up so users can't change the entries. Allowing changes would defeat purpose of an audit trail. If you need help with problems you encounter for this new effort, start a new post and we can show this one as solved.
