Summarize data from a subreport in a main report

Question

Good afternoon,
I'm trying to summarize data from a subreport with data in a main report and I can't get it to summarize all the data correctly. The reports are linked on order number.
The main report has 3 groups - customer id, batch, order number (in that order). In the detail section I have product and amount. I have the group footer for group order numbers split into two. Footer A has the subreport.
The subreport has tax code and amount in the detail and I've created a shared variable:
WhilePrintingRecords;
Shared CurrencyVar taxtotal := Sum ({@total tax})
In my main report I created a formula for the shared variable:
WhilePrintingRecords;
Shared CurrencyVar taxtotal; taxtotal
In Footer B of the order number group I have a summary field that is taking the shared variable and adding it to the product amount and creating a total.
{@taxtotal1} +Sum ({@ext price}, )
That is all working fine. Where my problem comes in is on the footer for the Batch group. There are 3 order numbers for 1 batch. I have this summary field in the Batch group footer
({@taxtotal1} +Sum ({@ext price}, ))
But it's not calculating correctly. I need it to take all the product amounts and all the tax amounts and add them together, what it is doing is only adding one of the tax amounts along w/ all the product amounts.
What am I doing wrong? Any help would be greatly appreciated.

Hi Jeanette,
You need to have the running total accumulate into the Batch group as well.  Right now it's just getting the the Tax Total from the last Order Number. 
In the formula in Footer B of the Order Number, change your formula to: 
WhilePrintingRecords;
Shared CurrencyVar taxtotal;
CurrencyVar batchTaxTotal;
batchTaxTotal := batchTaxTotal + taxtotal;
taxtotal;
Now in your formula in the Batch footer change it to: 
WhilePrintingRecords;
CurrencyVar batchTaxTotal;
(batchTaxTotal +Sum ({@ext price}, {batch}))
In the Batch Group Header, you will need to reinitialize the total to 0 for the next batch: 
WhilePrintingRecords;
CurrencyVar batchTaxTotal := 0;
Good luck,
