2 Questions from an amateur crystal developer...

Question

Hi all,
Ive got a couple of questions as im just starting out with Crystal.
I have a dataset returning Investors, their commitment amounts, the tax code and their contacts. My problem is that for each contact, a new row is created in the DB, the one investor will appear 4 times if they have 4 contacts. e.g.
Closing Date: 01 Sep 2007
Investor 1           £1,000,000           1234          Contact 1
Investor 1           £1,000,000           1234          Contact 2
Investor 1           £1,000,000           1234          Contact 3
Investor 1           £1,000,000           1234          Contact 4
What we need to do is get all the values on the one line, with the contact concatenated together e.g.
Closing Date: 01 Sep 2007
Investor 1           £1,000,000           1234          Contact 1, Contact 2, Contact 3 and Contact 4
Please notice that the contacts are first separated by comma's, and then for the last one it is an 'and'
How would this be done in a formula? I am currently grouping in Closing Date, but can group on investor as there are multiple investors per closing date, and im sure crystal needs to know which investor to use to concatenate the contacts.
My second question is how do I summarize the commitment values. As their are multiple rows returned for each investor (due to the contacts), it sums up the same value multiple times, even when I want it just summed once. For example:
Investor 1           £1,000,000           1234          Contact 1
Investor 1           £1,000,000           1234          Contact 2
Investor 2           £3,000,000           1234          Contact 1
Investor 3           £2,500,000           1234          Contact 1
The sum of this is currently £4,000,000, but i want it to be £3,000,000 as Investor 1 only has 1 commitment amount, not 2.
Hope all of this makes sense, if it doesnt i can clarify further.
Thanks in advance.
Rob.

Huzzah for lazy!  You could have assigned the output of that formula to a variable, and then just displayed the variable in the group footer... saves a bit of processing time/memory I suppose, but we've all got super-quick PC's, right?
just change end of the existing formula in the group header to:
...groupcounter:=groupcounter+1;
stringvar thegrouptext:=grouptextsuffix" Closing Date";
and in the group footer have simply:
whileprintingrecords;
stringvar thegrouptext
Anyways... that last problem.  Yeah, it's calculating a grand total so you can display it at the end of the report.  If you just want the total for the group, place the field into the group footer, or just add in a summary/formula to calculate the minimum from the group:
minimum(,)
Actually, now I've tought for a second, if you stuck that on the end of the existing formula, that'd work - it'd add to the grand total, then display the group total. Unsuppress it if it's already suppressed!
