I have a database that tracks the duties completed by cetain users. One of my tables has 10 questions with a yes/no data types.
The questions are a subform and query based. What I have to do is count each yes and each no for all 10 questions on a daily bases, then find a overall total and precentage. The problem is I'm not sure how to count each question, especially if QuestionA is yes for day1 and no for day2. Does this make since? If so i would really appreciate some help.
Thanks
 
Well, we know that in a yes/no field, a YES or TRUE equates to -1 (negative one) and a NO or FALSE equates to 0 (zero).

So if you sum the yes'es and multiply by -1, you'll get a postive 'sum' of them, and if you count up the NOs you'll get a count of them.

You could also COUNT the YES'es, but you probably shouldn't SUM the NO's...

Since all of your questions appear to be separate records, you'll probably need some sort of domain aggragate function (not to be confused with a domain AGGRAVATION function..) to sum/count them up:

Q1Count =
DCount("Question1", ID = {ParentKEY})

Where you are counting (true's only) the question 1 values for a particular person.

IF you have a fixed number of questions, you can also get the NO's by subtracting the YES'es from the fixed count.

Hope this gets you on your way...
