I am using cr8.0

You should be referring to group and report sections, not "lines". If you mean you have a count at a group level, and you want a percentage based on the grand total, then use a formula like this:

count({table.entity},{table.groupfield}) % count({table.entity})

Not sure whether you want this to be a distinctcount or not, but edit as necessary.

Ok, I got this one -- here's another -- when I try to total a column containing a formula which is

sum (calculation)

I get the error message:  The summary / running total field cannot be created.

I am using cr ver 8.0

Is there any way around this???

Thanks in advance.

You need to show the content of the formula.

Sorry I wasn't more expedient on my reply -- still
learning the group protocol.

Anyway, in the Group 1 Header I have the following:

    column for item numbers
    column for count of item numbers
    column for sum of weight
    column for percentage of sum of weight
    column for pieceweight
    formula @pcs
              sum ({wt},{item})/{piecewt}

the above error occurs when I try to total @pcs

I am truly appreciative of your support!
 

First, I believe you are in the wrong forum--try forum149: Business Objects: Crystal Reports 4 Other topics or forum767: Business Objects: Crystal Reports 1 Formulas in the future.

You cannot insert sums on formulas that already contain summaries or that use any function that requires a sequential evaluation of records, like Previous() or next(). In this case, you would need to use a variable to sum your formula. The following assumes you are summing at the grand total level:

//{@accum} to be placed in the section containing the {@pcs} formula:
whileprintingrecords;
numbervar sumpcs := sumpcs + {@pcs};

//{@display} to be placed in the report footer:
whileprintingrecords;
numbervar sumpcs;

This worked very well -- I thank you.

I will certainly look at the other forums if I need further help -- Thanks again.
