Me is an implicit reference to the class you wrote the code in. In context of Access, most of times, it's the forms or reports.
So therefore, if you have a form named "MyForm", the full and explicit referencing syntax (to get its name property for this example) is:
Forms!MyForm.Name
But when you're writing code in the module for the MyForm, you can shortcut the explicit reference into:
Me.Name
Did that help?
