Sub form reference

[adz2013]

I am trying to reference a sub form on the main form. This is what I am useing:

Me.ahRating(control on the main form) = Forms![MainFormName]![SubFormName].Control On SubForm

I have used it before but now I am getting a message that says "Object doesn't support this property or method". Does anyone know how to fix this?

Thanks
