Question

When I pass a value from main report to subreport it is showing as 0 crystal reports. What can be the reason?

On the main report I created a variable

WhilePrintingRecords;
Shared Numbervar x;
x := SUM(tble.value);

On the subreport

Whileprintingrecords;
Shared numbervar x;
x;

x shows 0 no matter what I do :( Help please.

The main report is linked to subreport by an ID .

公式在主报告中的位置（哪个部分？标题/组/明细）？

您可以在子报告中使用evaluateAfter（{@ formula_name_here}）作为公式，这可能有助于解决问题。
