Crystal Report 3 formula trick - calculation formula

I am trying to complete a 3 formula trick to calcalate a grand total from a group total.

so far so good except I seem to have a road block in the calculation formula and get an error that a 'Number" is required here when I drop in my group total field to calculate. I have tried to use a conversion to no avail. And that field data type IS a number in the report.

See attached.

thanks

The problem is that according to your formula, you are trying to sum the Company name - which will cause an error. Unless I'm missing the point, if it's a grand total then you don't need to sum the group totals, just sum the individual field.

If you want to know the total at specific points, then try a running total.

Gotcha - That is what I figured...but have tried many variations on this.

Running total won't work on a summarized field in a group...I so wish it would - hence using the 3 formula trick - I am CR9 btw.

When I try to use the actual field amount, which is a currency datatype, I get the same error - see attached...

gordon2011 - Sum({Activity.Amount},{Name.Company})
That calculates the sum of Activity.Amount over the group for a company.
It limits the values in the sum to the records for the company. Other wise it will sum all values in the report.

changing to Global CurrencyVar did it!! wow - I knew I was close - funny how it would not let me change the data type within the last statement on the calculation formula - I did have to go into all 3 formulas and change the GrandTotal variable datatype to currency and then I could put in the formula that calculated the group totals and wallah - it worked.

thanks

now I think I am supposed to do something with points...I dont do this often - once a year or so.....
