use updated variable in subreport

Hello everyone,

I tried to use an updated variable, returned by my subreport 1 (a total) inside my subreport 2.

But my variable has only the default value, not the updated value from subreport 1.

Is it possible to pass an updated value to a subreport, or it will always take the default value ?

I will add some screenshot soon to explain better.

Thanks for helping !
