VBA Menu userform stays up hidden workbook

I created a userform that is a menu that has a command button for each sheet in the workbook.

I entered the code below and have gotten it where the menu will open with the workbook staying hidden however, even you click on the command button nothing happens. I need it to open the selected sheet so it can be edited while still keeping the menu open.

I've searched through other posts on multiple sites and can't find a solution to make it work better.

Private Sub CommandButton1_Click()
    ThisWorkbook.Sheets("Availabilty").Activate
End Sub

Private Sub CommandButton2_Click()
        ThisWorkbook.Sheets("Assignments").Activate
End Sub

Private Sub CommandButton3_Click()
    ThisWorkbook.Sheets("Daily Schedule").Activate
End Sub

Private Sub CommandButton4_Click()
    ThisWorkbook.Sheets("Sign-Up").Activate
End Sub

Private Sub CommandButton5_Click()
    ThisWorkbook.Sheets("Sign-Up Tracker").Activate
End Sub

Private Sub CommandButton6_Click()
    ThisWorkbook.Sheets("Gap Coverage Tracker").Activate
End Sub

Private Sub CommandButton7_Click()
    ThisWorkbook.Sheets("Control Schedule & Sign-Up").Activate
End Sub

Private Sub CommandButton8_Click()
    ThisWorkbook.Sheets("Help").Activate
End Sub

Private Sub Image1_BeforeDragOver(ByVal Cancel As MSForms.ReturnBoolean, ByVal Data As MSForms.DataObject, ByVal X As Single, ByVal Y As Single, ByVal DragState As MSForms.fmDragState, ByVal Effect As MSForms.ReturnEffect, ByVal Shift As Integer)

End Sub

Private Sub UserForm_Click()

End Sub
