Form Controls Option Button

I cant get this to work, it comes back with run-time error '424': object required

I am using form controls option button not activeX controls.

HTML Code: 

Sub OptionButton12_Click()
If OptionButton12.Value = True Then Range("D14").Value = "Alamo"
End Sub

Sub OptionButton13_Click()
If OptionButton13.Value = True Then Range("D14").Value = "ERAC"
End Sub

Sub OptionButton14_Click()
If OptionButton14.Value = True Then Range("D14").Value = "National"
End Sub
