Control buttons will not work

I am having a problem that I can't find the source to and need some help. I

have a form set up in a tab (4 tabs- Contacts, Registration, payment, 
Contribution)
In the main form Contacts I have Control buttons for: First Record, Last 
Record, Find Record, Previous Record, Next Record, Close

Here is the problem: The First Record button and the Last Record Button
when 
clicked do nothing. The Find Record Button when clicked gives a message
box 
"You Can't Use Find or Replace Now" The Previous Record and Next Record 
buttons when clicked give the same message "You Can't go to the Specified 
Record" The close form button works fine.

I cannot find out why these buttons don't work. I tried creating another 
button and those do not work either.

Here is a copy of the Find record code and Previous record code if anyone 
can help please advise thanks

Private Sub Command63_Click()
On Error GoTo Err_Command63_Click
    DoCmd.GoToRecord , , acPrevious
Exit_Command63_Click:
    Exit Sub
Err_Command63_Click:
    MsgBox Err.Description
    Resume Exit_Command63_Click
End Sub

Private Sub Find_cmd53_Click()
On Error GoTo Err_Find_cmd53_Click
    Screen.PreviousControl.SetFocus
    DoCmd.DoMenuItem acFormBar, acEditMenu, 10, , acMenuVer70
Exit_Find_cmd53_Click:
    Exit Sub
Err_Find_cmd53_Click:
    MsgBox Err.Description
    Resume Exit_Find_cmd53_Click
End Sub

Thanks in advance for you help
