Hello

I have a simple Crystal Reports project I m gonna have a simple sub-report too.
I always get "Missing Parameter Value" error.

I want to have sub report for each record of main report. I have searched a lot on the Internet for almost a week but There hasn't been any visual example or sample which includes:
(MainReport + subreport and dynamically passed parameter from main report to sub-report and then to stored procedure in SQL) all examples are programmatical manners like this answer:
rptH.Subreports[1].SetParameterValue("@your parameter name", parametervalue);
but I cant pass "parametervalue" from C# code because I want to load each record in main and pass its ID of each record to sub-report dynamically.

But I want to pass parameter from Main Report after each record loaded not from C# Code.

I'll be grateful if someone help me.

What I have tried:

I added a main report and linked it to a model. then I added a parameter field value named ID. Then I added a subreport and added my SP to It . Again I went to main and a made link to Parameter field value and SP ID.
