Essbase Error(1200370) while executing business rule

Question

Hi,
I am getting the error - Cannot calculate. Essbase Error(1200370): Error executing formula for [Average] (line 15): attempt to cross a null member in function [@X]
on executing the following script-
FIX(@RELATIVE("AltHierarchyProducts",0))
FIX("FY13","Draft1","Budget")
"Average"= @MEMBER(@CONCATENATE("P", @NAME (@PARENT(@CURRMBR ("Products")))))->"Variable" * (("Sales"->"Month1+ "Sales"->"Month2" +"Sales"->"Month3")/3);
ENDFIX
ENDFIX
"Variable" is an account dimension member. When I remove the '->"Variable"' part, the script executes, but obviously gives no result since the account member is missing.
I have read a lot of posts on this error but could not resolve this issue.
A basic view of the hierarchy is as under -
Products -
AltHierarchy
--Cat1
---Prod1
---Prod2
--Cat2
---Prod3
---Prod4
PCat1->"Variable" and Pcat2->"Variable" are the placeholders where the variable values are stored.
Please help.
Thanks.
Note: I am using Essbase 11.1.2.1

Is it possible that your @MEMBER function never actually returns anything. You have assumed that it works but perhaps it never works and it is only when you add the cross-dimensional operator that the issue becomes apparent.
e.g. If it is not working:
Without cross dim: "Average"= @MEMBER()* (("Sales"->"Month1+ "Sales"->"Month2" +"Sales"->"Month3")/3);
I'm not sure but perhaps the above will return something like #missing* (("Sales"->"Month1+ "Sales"->"Month2" +"Sales"->"Month3")/3)
With cross dim:
"Average"= @MEMBER()->"Variable" * (("Sales"->"Month1+ "Sales"->"Month2" +"Sales"->"Month3")/3);
Which I would assume would fail.
Do you see what I'm getting at? You could test that theory fairly easy.
