Crystal Report for next loop syntax issue

THe loop in your idea will execute fully each time the group footer is displayed.

I think what you want is this

In the report header add a formula
WhilePrintingRecords;
Global NumberVar i;
i := 1;
''

In the groupfooter
WhilePrintingRecords;
Global NumberVar i;
i := i + 1;

Hi Thanks for the reply but I really want a limit of i = 1 to max where max is a value in a table.
When I complete the group calculation, I would like to increase i + 1 until I reach the max value and the report would loop again until max was reached

Thanks

The report goes through records one at a time.  There is no way to loop again?

What are you trying to do with this?
Are you trying to get a record to display several times?

The report looks at a formule and uses the value 1 (i)  in the calculation (multiple places) (loop i+1)
the report looks at the same formule but uses the value 2 at (loopi +1)
until maxvalue.
I will return approx 200 lines (from my data) of different results as I will use i as a group below the group I am summarising)

Is this any clearer?  Thanks

Chris

Not really.

Can you show a sample data and where the values would be used?

Already thought of creating a dummy table in Sql but was really looking for a more elegant approach.  Thanks for your asisstance guys

FWIW, you don't necessarily have to create a new table for this.  Basically, you just need a table with at least as many rows as you'll need iterations for your calculations.  But there are a couple of caveats.

 1) Ideally, the table would include record numbers, so you could use the record selection to control how many records the subreport reads (record_number_field <= max_capacity).

 2) Without a record number field, you'll have to use suppression, which means that CR will read every record and just not show the "extras", so you'd look for some table (or group of records within a table) that had as many records as you'd ever need, but not much more, to try to minimize the reading of unnecessary records.  For example, if max_capacity will never exceed 100, a 10,000 record table is probably not a great solution.  :-)

Thanks James thats useful infomation.

No problem.

 I should explain that my point in # 1 was that if you have a record number field that you can check in the record selection, that test will hopefully be passed to the server, so the server only sends the required number of records.  I just realized that I hadn't explained why you'd want to have a record number field and check it in the record selection.

Thanks James.
I have overcome this issue and have a nice loop, and have another which I have just published.
Thanks again

No problem, again.  :-)  Glad you were able to work it out.
