IIf function problem and serial number for each records on the report

[Peter]

Dear all,

Would you tell me how to solve the following two problems in an access file
upon preparing report form:
a) I have written an IIf function for a string field at the beginning of
group row of a report form as below:

sss is a string field with 2 characters;
the function is = IIf([sss]="1", "yes","no")

Problem: the report only shows the "#¿ù»~"

If the function is =IIf([sss] Is Null, "yes", "no"), the result is
only showing "yes" for all records.
b) How can I list out the records on the report with serial numbers if
there is serial numbers for the records in the table?
Thank you!!

Peter

Unless others have figured out exactly what you mean, post your SQL from
your query.

What is the structure of the table in question?

Dear Tim,

a) I generate a report from a query table, then I want to use this
report
to show the total numbers of the customers who buy the goods. There is a
string field "choose goods" in the table. Such field only contains either
"1" or "". Therefore, I write the IIF function on the report form at the
beginning of group row:

=IIf([choose goods]="1", "No. of customer to buy the goods", "No. of
customer not to buy the goods")

The expressed result is : No. of customer to buy the goods
99999
No. of customer not to buy the
goods 99999

However, the result is "#??" 99999
"#??" 99999
b) I make a mistake on my question. There is NO a field to indicate the
serial number of the records in the original table. As I want to general a
report from a query table under certain conditions, only some records will
be selected. How can I general the serial numbers for each records on the
report, such that:

1 xxxxx xxxxxxx xxxxxx
2 xxxxx xxxxxxx xxxxxx
3 xxxxx xxxxxxx xxxxxx

To question B

My way to do this is to put in the Table a numeric field with name
"DumNr" or so, with only "one" in it, I mean the number 1. DefaultValue
also put to 1.

If you create this field afterwards you could find this action query
useful:

update mytable set dumnr = 1

In a query you have to generate an extra field like this:
dumnr: 1

In any report where I want to number the rows I put a textfield with any
name, the Property ControlSource set to dumnr and the property
RunningSum set to 1 or 2.

1 will restart numbering again and again after every grouping.
2 will number all rows in the report without restarting.

This works in a report. I didn't find a way to do the same in a query
