Default Calculating Averages

I am trying to calculate an average on the following

[score A]+[score B]+[score C]+[score D]

These are text fields with validation rule

="NA" or Between 1 and 5

I know that the Avg and Sum functions omit Null values but how can i get it
to omit "NA" and what is the function for calculating the average.

I try to calculate the average using

=Avg([Score A])+Avg([Score B]), etc.

but it does not work.

Please help.

Default Calculating Averages

Try the following.

Avg(IIF([Score A] = "NA",Null, Val([Score A])))

Avg(IIF([Score A] = "NA",Null, Val([Score A]))) +
Avg(IIF([Score B] = "NA",Null, Val([Score B]))) +
Avg(IIF([Score C] = "NA",Null, Val([Score C]))) + ...

I am not sure why you are adding the averages but if that is what you
want to do then this will work.

If you want the average score for A and the average score for B then you
need to do the calculation in separate fields.n

Good morning John,

I tried that but it gave me #error. I thought i might've been doing
something wrong.

I appreciate your help. Await your response.

Sorry, but I can't see why you are getting error returned. You might try

Avg(IIF(IsNumeric([Score A],Val[Score A],Null))

Does that work to return a value? If so, then try adding the other parts
one at a time and see if they work.

Default Calculating Averages

Good afternoon John,

I tried the other formula once again and it returned a value; it added
instead of averaging. Also, when i enter NA, it does not return a value at
all, it simply goes blank.

I apologize for the inconvinience and do appreicate your help with this.
What can i do to get it to Average instead of adding and to factor in the NA
in order to set it to Null.

Try

Avg(IIF(IsNumeric([ScoreA]),Val([ScoreA]),0) + IIF(IsNumeric([Score
b]),Val([Score B]),0) + IIF(IsNumeric([Score C]),Val([Score C]),0))

That will average in a 0 if all the scores are in the row are NA.

If that is not acceptable then you will have to write a more complex
expression that might look something like
Avg(IIF (IsNumber(A) + IsNumeric(B) + IsNumeric(C) = 0,
Null,
IIF(IsNumeric([ScoreA]),Val([ScoreA]),0) + IIF(IsNumeric([Score
b]),Val([Score B]),0) + IIF(IsNumeric([Score C]),Val([Score C]),0))

Good afternoon John,

The first expression you provided worked. That's great!

It sums up the numbers and omits any fields that have NA. I set the same
expression to count in another textbox which returns back the count of fields
with a numeric figure. I divided one by the other and obtained my average.

Thanks a million!!! You're a life saver!
