Crystal reports, sub-reports, and shared variables

Question

I have the @InitVars formula in the page title, which includes the following and similar lines:

shared numbervar runWaste:=0;

In the Details section, I have a summary report that has the @SetRunWaste formula:

shared numbervar runWaste;
if (OnFirstRecord) then
(
if not(isnull({x.x-or})) and 
not(isnull({x.y-override})) and {x.y-override} = true then
runWaste:={x.x-or} 
  else
runWaste:= {x.x}
);
runWaste

I see that the result of this formula in the subtask is 18.00.

However, both in the other unit and in the main report in the "Details w" section (as a test), I have the following @test formula:

shared numbervar runWaste;
runWaste;

In both places it is displayed as 0.00.

Why is it showing 0 not 18?

I am using Crystal Reports version 11.0.0.895.
