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.

----------------------------------------------------
Group 1

        row 1---------------------------  
        row 2---------------------------
        .
        .
        .
        row N---------------------------
--- I need here number of rows!---------------------

Group 2

        row 1---------------------------  
        row 2---------------------------
        .

        row M---------------------------

Total Rows: M+N

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
```

This solution may help someone,

Create a Running Total:

Choose a field
Select distinct count as Type of summary
Choose your group name in Reset section
Now drag and drop the running total field in group footer.

Refer the image below

This solved my problem Create new formula field

{IM_INV.QTY_ON_HND}-{IM_INV.QTY_ON_HND}+1

{Existing field} minus {exiting field} plus 1

This gave me a "1" next to each detail line in a field I called {NumberForCount}

Because it was made this way it showed up in running total field options

Then made a running total field like normal in the footer

Another way to try by using Summary

Right Click > Insert > Summary
Choose Field (I choose string value)
Choose "Count" to Calculate This Summary Combo box
Choose Summary Location in Where would you like to show this total
Then OK
