I have a drawing file with several sheets.  Sheet one I have a bill of material shown which contains some parts and some sub assemblies.  On Sheet  two I show one of the sub assemblies thats on sheet one and I go to the properties and check the box attaching it to the bill of material on sheet one.  But when I put a balloon on the sub on sheet two the get the following shown in the pic below.  I want the item number in the balloon to be what is called out on sheet one.  What do I need to do?
