Forms :: Go To Record If Duplicate?

On my form I've got an afterupdate event that checks if the information entered already exists and this works absolutely fine. However what I would like is the option to go to the existing record if one is found, but I can't get it to work.

This is my code currently;

Code:
Private Sub Job_No_AfterUpdate()
If DCount("*", "PACKING", "[Job No>]='" & Me.[Job No] & "'") > 0 Then
If MsgBox("Job Number already exists! Go to record?", vbYesNo, "DST PLANNER") = vbYes Then
Dim rs As Object

[Code].....

The check for the Job Number works fine but when I click Yes on the message box, the form stays on the current record instead of moving to the existing record.
