Formulated Calculations

Hello,

I am trying to build an "assessment" application that takes different grades and calculates overall scores. The issue I am currently having is that lets say I have three numeric fields that are 1-10, and a score field that takes the aforementioned three fields and sums them and then averages. How would I go about creating a calculation where if one of the grades were not applicable, it would average the other two without needing the N/A field to complete the calculation?

    Try this
    Average(
    IF([Field 1]<>"N/A", [Field 1 score]),
    IF([Field 2]<>"N/A", [Field 2 score]), 
    IF([Field 3]<>"N/A", [Field 3 score]))


    That will only average the non null values, so if field 1  = "N/A" it would be omitted from the Average.

    if you also need the sum


    IF([Field 1]<>"N/A", [Field 1 score],0)
    +
    IF([Field 2]<>"N/A", [Field 2 score],0)
    + 
    IF([Field 3]<>"N/A", [Field 3 score],0)

      Hey Mark, I'm getting the error that I can not use the <> operator with numbers or text.

      Also, I am using one Field for each graded question, so I am not sure how to manipulate what I am trying to do with your solution.

      For example, I will pretend I have the three questions:
      Wall Cleanliness: (1-10 numeric grade)
      Floor Cleanliness: (1-10 numeric grade)
      Window Cleanliness: (1-10 numeric grade)

      Normally, I'd take the three grades and average them for the overall 'cleanliness' score. But if the next location I go to does not have windows, I would need to omit that from the overall average of the 'cleanliness' score.

        I was now able to get it to work using your original code with a little bit of work.

        var number blank = ToNumber("N/A");

        Average(
        If([Signage Lit / Easily Viewable Day & Night]<>$blank,[Signage Lit / Easily Viewable Day & Night]),
        If([Reader Board Working]<>$blank,[Reader Board Working]),
        If([Entrance / Exit Obvious and Easily Understood]<>$blank,[Entrance / Exit Obvious and Easily Understood]))

        Thank you Mark!
