How to count number of grouped rows in the Crystal Report

I need to count and show number of rows of grouped data in the report. I already have number of rows of total data in Report Footer section (I used Count() function and that works fine), but I need to have total rows in the Group Footer section which shows number of rows of grouped data. The visible explanation of the problem is shown under.

Thanks.

Solution

Try the solution

Create a formula @reset. Place the formula in groupheader and supress
```
 Shared Numbervar count;
 count:=0
```
Now create one more formula @ Increment and place in section where there are rows I have assumed it as detail section and supress.
```
Shared Numbervar count;
count:=count+1;
count;
```

Now create one more formula @Display. Place this formula in Group footer

Shared Numbervar count;
Shared Numbervar Count_Final;
Count_Final:=Count_Final+count;
count;

Now create one more formula @DisplayFinal and place in Report Footer
```
Shared Numbervar Count_Final;
Count_Final
```
