Use a variation of this under the Lost_Focus event for the textbox in question:

   If IsNumeric(txtName.Text) = False Then
         Call MsgBox("Invalid input", vbInformation + vbOKOnly, "Please enter numbers only")
         txtName.Text = vbNullString
            Else
            txtName.Text = txtName.Text

  End If

If you need further help, you can email me directly. Good luck
