Q:

Passing Value from Sub Report To MainReport on Crystal Reports

I'm currently having a problem with regards on Crystal Report Shared Variable. this is my situation.
I have a Report consist of multiple sub reports (and of course the main report). i need to expose a value in main report from Sub Report, but the problem is i need to Display it before the sub report was rendered. Please see the image below:

As you can see the image above, i need to display the value below (Sub report with RED encircle with VALUE) on the TOP (Red encircle without value).
I used Shared Variable but i think it will not work since the TOP will be first rendered (where i need to display the Value from subreport) before the Below(where i need to get the value).
Is it possible? 

A:

The section that displays the value has already been rendered by the time the other section sets the value of the shared variable.
Two options:

add a second instance of the subreport to a section that precedes the section when you want to display its value; you won't be able to suppress either the section or the subreport, so you will need to make the subreport as small as possible and change the font colors to white
use a sql-expression field to calculate the desired value and avoid the subreport complexity altogether
