SubReport Data in a Main Report Yet Again

Question

I have been trying and reading posts all day.
1. The shared variable formula used in the main report will show any/correct value only if its placed atleast 1 section below the one where the sub report exists. (I've Done This)
2.The formula that is used inside the sub report needs to be physically placed on any of the sections within that sub report(you can suppress it to avoid displaying the value). (I've Done This)
3. Due to design constraints if you cannot move the sub reports from Report Footer then you can atleast mock them and place respective copies in the Report Header.These can contain just the summary values, thats it. Further, to nullify the display effect you can suppress all the sections of these sub reports and make them so small such that they appear as tiny dots and place them in extreme corners of the Report Header section. (Not sure this would apply since I have met #1 and #2)??
The blue outline/highlight is the passed total from by first subreport locatd in Group Header 1b. As you can see it is passing 0.
In the subreport, here is the formula used to get the OrderQty.
WhilePrintingRecords;
Shared NumberVar OrderQty;
OrderQty := OrderQty + {iptrn.ipqord}
I am using the "three part" formula to to calculate the Qty because when using a sum it sums up all records and I need to to sum by change in item. The subreport is calculating correctly. I have also tried a running sum but this won't pass either and I get messages about not being able to use the formula with itself so gave up that avenue.
In the main report, here is the formula used to display the OrderQty.
WhilePrintingRecords;
Shared NumberVar OrderQty;
OrderQty
//@MainFormula
//Returns the value that was stored in the shared number variable called
//OrderQty in the subreport
I think I have this all correct but still getting zero so i am not sure if it has something to do with resetting the value and maybe my linkages are not correct? Any help will be appreciated. I have very little experience with Crystal and less with sub reports.

Answer 1

Ok, so I used the example sent and I can't really tell you why it worked but it did. The modifications I made were so minor I would never have expected it to work.
here is one
Mine
WhilePrintingRecords;
Shared NumberVar OrderQty;
OrderQty := OrderQty + {iptrn.ipqord};
Yours
whileprintingrecords;
shared numbervar OrderQty;
OrderQty:=OrderQty + {iptrn_.ipqord}
The only difference I see other than the capitalization is the space after OrderQty :=.  My numbers were working fine on the sub report, they just wouldn't pass to the main report.  I did move the reset to the page header like your example but I don't understand why that even works when it should reset on the item, not the page..??? I also put the details variable in a second detail section like you had in the example. What is the theory behind this?
I also had a second one that I needed so I set that up exactly as the first one and no go. I had to move the reset into the GH1 and I put the details variable in a second detail section and it too worked.
I can't say that I understand why......I'm happy it works but it would be nice to know the why so next time I wouldn't struggle with it
