Calculations in repeats not updating

SébastienDebar

I have an inspection form with repeat. The repeat in the survey contains two questions. The first is about the presence of trees, and the second is about the number of trees (if the first question is Yes). In the repeat, I have a field that takes the value of the second question (if the first question is Yes), otherwise it takes the value 0. I have another field that sums up all the trees.

type	name	label	calculation	relevant	bind::esri:parameters
begin repeat	Tree	<center>Tree
select_one yes_no	Trees_Present	Present of trees :
integer	Trees_Number	Trees :		${Trees_Present} = 'yes'
integer	Trees_Total	Total :	if(${Trees_Present} = "yes", ${Trees_Number}, 0)		calculationMode = always
end repeat
integer	All_Trees	Total trees :	sum(${Trees_Total})		calculationMode = always

When users were filling out the survey recently, they noticed that moving back and forth between repeats to make corrections locked the calculations and the totaled sums could no longer be updated. I have tried calculationMode = always.

 

I am using Survey123 version 3.22.49.

This "refresh" button indicates that either someone typed into the field, or something more annoying is going on (could be a few vague things...). Clicking the button should show the correct values.

1. Calculated fields should be hidden or locked. This prevents users from interfering with them. Locked/hidden calculates also tend to work better than visible and unlocked calculations. 
   
   
2. Repeats are annoying for calculations. In very general terms, when the last thing in a repeat is a number needed for a calculation, the user needs to manually press "enter" for the calculation to trigger. Entering the value and then immediately going to the next tab skips that step and required them to go "back" and then "forward" in the repeat for the calculate to work. A more elegant solution is to use the "numbers" appearance. This does everything for you, ensuring the value is entered and the calculate triggers. 
   
   
   
3. ${Trees_Total} is unnecessary for the survey as-is. You can drop it entirely and save the hassle. 
   
   
   
4. <calculationMode=always> should not have spaces. Spaces means it isn't working. 
5. This will have zero impact on your calculations, but I always like mentioning it. Swapping <${Trees_Present} = 'yes'> to <selected(${Trees_Present},'yes')> is a good practice. Far more flexible. In this case, they will have the same effect.

Try some of the things I have listed above. There are probably a few things on their own that will resolve the issue. But there are several "best practices" that should not only fix that issue, but prevent future issues as well.
