Printing null values in Crystal Reports 10

[agreen10]

If you have three tables: I want all the data from table a and b and matching data from table c only that table c contains nulls or blanks. How can I join these tables to work.

Table relationships require more information than "data from table a nd b.

And what would matching data from C mean if they are null, do you mean that you want the nulls from A and B, because if they match they'll all be nulls, right?

GEnerally people will post example data to aiid in postings.

It sounds like you want to join A to B, then a left outer to C, and in the report->edit selection formula->record, palce:

isnull(c.field)
or
c.field = ""

Hard to say exactly, try taking a few moments to think through your post and supply sufficient information in the future.
