Development Access Gurus - Disabling a button

Basically I have made two buttons (next and previous) which navigate the results from a query on a form.

What I want to do is make it so that the appropriate button is disabled when there is no next/previous record. Otherwise it goes on to the next set of results which I don't want it to do.

How would I go about doing this, can I do it through access or would I have to add it to the VB code?

current code:

 

Code:

Private Sub cmdGotoPrev_Click()
On Error GoTo Err_cmdGotoPrev_Click
If Not CurrentRecord = 1 Then
    DoCmd.GoToRecord , , acPrevious
End If

Exit_cmdGotoPrev_Click:
    Exit Sub

Err_cmdGotoPrev_Click:
    MsgBox Err.Description
    Resume Exit_cmdGotoPrev_Click
    
End Sub



Private Sub cmdGotoNext_Click()
On Error GoTo Err_cmdGotoNext_Click

If Not CurrentRecord = DCount("*", RecordSource) Then
    DoCmd.GoToRecord , , acNext
End If

Exit_cmdGotoNext_Click:
    Exit Sub

Err_cmdGotoNext_Click:
    MsgBox Err.Description
    Resume Exit_cmdGotoNext_Click
    
End Sub
