Custom Calculation in ASO - Error in MDX query

Question

Hi All,
We are trying to use a run a custom calculation on our ASO cube
We are getting the error as below
Syntax error in input MDX query on line 13 at token ' )'
When i checked my POV i did not find any issue. Even when I try to put only one crossjoin, it is still giving me the error saying "error at line 2')' "
I am unable to find the cause of this issue.
Can any one help me on this.

You've got a mismatched " in the first line of the "execute calculation" statement.
However, I think the real problem is in the calc script.  I don't believe you can do this in MDX:
CASE WHEN x THEN
    a := y;
    b := z;
END
You have to do this:
a := CASE WHEN x THEN y END;
b := CASE WHEN x THEN z END;
An alternative is to create a formula member for each of the measures you are trying to set (with the member formula containing the CASE logic) and have the calc script copy the formula member to the permanent member.
