How to add grandtotal to a crystal reports crosstab report

I created a crosstab crystal report (2013). I have it in a group header, I want a grand report total for each column: fluidspart, shopfee, standardlabor, standardpart, standardservices, tirepart. I'm not sure how to go about doing that part. Picture can be found here of the report:

Solution

Take one more cross tab in Report Footer and place all the fields that you have place in first cross tab and display.

Edit---------------------------------------------------------------------

To get the prefix

Assuming your parent database field is parent.

Create a formula @Prefix write below code and use that formula to group.

{Parent}[1]+{Parent}[2]

This will pick RC and group by the formula

Edit2------------------------------------------------------------------------------

Follow below process to supress.

Create a formula @Reset and place in group header.
```
Shared Numbervar count;
count:=0
```
Create one more formula @Increment and place in details.. if your customers are in detail
```
Shared Numbervar count;
count:=count+1;
```

Now in supress of the Parent group footer write below formula.

EvaluateAfter({@Increment});
Shared Numbervar count;

if (count>1)
Then true
Else False

This will supress the group total
