Look Up Function

[Guest]

I have a class summary report and i would like to find the number of missing
assignments. The missing assigment report is from another query. Is there a
way i can create a formula in my summary report and obtain the information
from my missing assignment query. Thanks you in advance.

If the query return only one record, you could write in the control source of
a text field in the report

=DLookUp("FieldName","QueryName")

If you need to sum few records that return with this query use Dsum instead
=Dsum("FieldName","QueryName")

Thanks for your help! I have another question for you.
I am trying to count the Completed Assignments field, which is a "Yes" and
"No" Data Type and place the information in the summary report. I am trying
to obtain a count of students who missed their assignments. I am using the
following formula: By the way, "Class Assignments Missed" is a Query.

DCount("Completed Assignments","Class Assignments Missed")

When i use this i obtain an error.

Thanks

To "count" the number of No values in a field named "MyField" in a report,
add a text box to the report footer (or group footer) with a control source
of:
=Sum([MyField]+1)
This works because the YesNo field stores a value of -1 for Yes and 0 for
No. Adding 1 to these values results in yes=0 and no=1. Summing the
expression results in a count of No values.
