Default Recording the frequency of Yes/No Fields

Thanks Allen. I will run with that and let you know how it goes.

Thanks for your patience.

Create a query. In the Criteria row under the number field:
0


That will eliminate all the records where the number as zero.
(Presumably you don't have negatives.)

Or you can put a text box on the report if you wish.
Set its Control Source to:
=([YourNumberFieldNameHere] 0)

Thanks Allen, your suggestion makes perfect sense but I forsee that being
a
problem when I'm creating the reports. How do I indicate that the incident
occured in the report? I'm certain the report query will bring up the
corresponding frequency provided the incident occured, however I would
like
to display a checked checkbox alongside the frequency. How can this be
done?
Sorry if my questions are too basic, I'm a newbie in this field.

you get away with just the Number field?

If the answer was No, presumably the Number is zero. It seems to me that
this would be a better (more reliable) design, as it would prevent the
existence of bad data (e.g. where the Yes/No field contains No, but the
Number field contains 8.) Having just the Number field avoids that kind
of
inaccuracy.

Hi all,
I'm designing a database that requires users to specify the number of
times
a Yes/No field occurs. This number is not required if the choice is No
but
if
Yes, I plan to create a drop down menu for the user to specify the
number
of
times the choice occured.
My first thought is to create a Frequency field for each choice but
then I
thought there must be a better way to do it. I came up with an idea to
create
a Frequency table (tblFrequency) described below:

tblFrequency:
Field: FreqID
Field: Freq

I'm planning to make FreqID a foreign key on my Incidents table which
contains the choices (Yes/No) fields.

The problem is that I'm somewhat short of ideas on how to make this
work.
Thanks for your patience.
