    Sum part of repeating field


      Any one know if there is a way to return a sum of part of a Repeating field?

      I have a numeric field with 30 repetitions; I'd like to be able to display the first 15 in the normal way, but then I want to have a calculated field next to those that shows the sum of the remaining repeating fields (repetitions 16 - 30).

          Sounds like you shouldn't be using a repeating field for this, but


          Field[16] + Field[17] + field [18] + and so forth.... + field [30]


          Will compute the desired result as long as you use your field name in place of "field" and spell out all the repetitions instead of "and so forth..."

            I thought it'd be a bit tidier using a repeating field; I've not really used them before and thought this would be a good case to try it out.

            Guess I'll go back to the trusted separate fields.

            Thanks for your help.

              I hope that doesn't mean 30 separate fields.  That would be almost sinful.  If so, I recommend that you create a related table to store that data.  Repeating fields should really only be used for display purposes.

                +1 for David's suggestion.

                I strongly encourage you to go that way.

                Separate fields is certainly the worst way.

                Though I discourage the idea, the sum of repeated fields would be relatively easy to set up.

                Field[16] + Field[17] + field [18] etc


                But it would be quite helpful if you can provide a more meaningful description. The idea of the reps 16-30 representing some different attribute as compared to 1-15 seems odd. What is this really all about?

                  I appreciate its not the best way to go about it, having multiple separate fields, which is why I thought the repeating field would be a good idea in the first place.


                  It's for gathering the required quantities of different materials on each floor of a building.

                  I have an Estimate table that has a related table called Quantities. Displayed in a portal on the Estimate layout, the users can select a product in the first column of the Quantities portal, then, they want to be able to enter the quantity required on each floor (that's what I was planning on using the repeating field for, the different floors, Ground - 29th).


                  The reason for trying to sum the last half of the floors was to truncate a printed report; where the quantities for Ground to 15th floor would be displayed, and then a sum of the remaining floors, so I could fit them all on a page.


                  Is there a better way of trying to accomplish what I'm trying to do? I'm sure there probably is, but I got a bit stuck on how best to add a product, then add different quantities for different floors for that product, in the Estimate layout.

                    As others suggested, use a related table with one related record in place of each repetition. If each record has a product ID and a quantity, you will have a number of options available for summing groups of records where the product ID is the same.

                    are all possible options to get the needed sub totals.
