i got a question about variables in inno

[ahmedwaill]

well i don't think that i can really do it since i'm not that experienced in codes stuff, can't you tell me how to do it ?

[Setup]
UninstallDisplaySize={code:Size2}
{Code}
var
Size2: Longint;
function UninstallSize
Size2={#Size}*1024*1024;
end;

something like that ?
PS in the code section i wrote it as {Code} cuz it will end the CODE box in the site... i know that it should be [ Code ]
