    Calculation in an add instance


      I am trying to use an if statement in an addinstance of an interactive form.  Based on the results of one field in the addinstance, I want to sum a different field from the add instance.  So, the customer can add any number of rows and choose from a drop down (coded 1-4) the position of the person.  If that position is 1 or 2, I want to sum the salary field in a calculation box.  If the position is 3, then I want to sum the salary(ies) in a second calcuation box, and if the position is 4, then I want to sum the salaries in a third calculation field.  My code for one of the the calculation field looks like this:



      1]::calculate - (FormCalc, client)


      if (detail[*].PTFT < 3) then







      The other two fields are the same except that they change "<3" to "==3" or "==4". 


      The problem is that it does not sum the second or third calcuation field.  Only my first calcuation field will work. 



      Since it is a rather simple if statement, I think that the problem may be in the subforms, possibly?


      Please see my form at http://www.units.muohio.edu/lifelonglearning/forms/zzztest.pdf


      Thanks in advance for any help you can lend.

          Ok I had a look at your form (nice form by the way ...good job). The expression you are using to determine the number of instances is not correct....as well when you sum the salaries it is the details subform that has th eiccurance numbers so that needs the * notation. Here is the 1st calc modified


          if  (details._detail.count < 3) then







          You also have the same code on the layout ready and the calc event. No need for both ...just leave it on the calc event and when the user enters the amounts the totals will update.


          You are also getting an error when the row initialize .....a partNoScript is being called becuase of script behind the Name field (itis called txtPartNo in your form). My guess is that you copied this from the Purchase Order sample and forgot to remove the scritp from the Initialize and the change event. This field was originally a DD field and that is what was used to populate it.


          Hope that helps

            Paul, Thanks so much, but not yet a go

              The code you suggest works, but does not give me the desired results.  Don't I have to use the detail.PTFT?  What is happening now is that if the first row details.detail.PTFT = 1 or 2 then it sums all the salaries in the MU employee salary box.  If details.detail.PTFT = 3, then it sums all the salaries in the MU student salary box.  I want it to evaluate each row individually based on that PTFT and sum in one of the two boxes.


            In words, I hope that:

            numTotal[1] = sum details.detail.salary where details.detail.PTFT < 3 for all instances of the table.


            Additional help?  Thanks so much Paul!

              I think I misunderstood what you are trying to do ....so if I select full or part time in the PTFT field I need to add all of those salaries into the 1st total. Then total up all of the benefits for the matching rows. Then I need to calculate the salaries of all rows where the user chose Student and calculate those salaries and benefits ....right?

                Now you got what I am trying to accomplish.  Thanks so much

                  Here is my concoction.....I removed the references to the partslist I mentioned earlier and I took a different approach to the addition of th efields. I had to use javascript because it allows a for loop which is required to accomplish the task. I wrapped the commands in an if statement to check if there are values in all three fields in the 1st row...other wise a number of errors is generated. You had a numch pf code on the layout ready events...I removed most of it as it was a duplicate of what was on the Calc event. There are still errors generated but I do not want to mess with what you already have. .....but it is working the way I think you want it.


                  Let me know
