Hi all,
will someone please help me. I've also googled old discussions, but can't
find it. I think this should be straight forward, but I can't figure out
how to script the following constraint. One one screen, I have three fields
-- Total, A, B.
I want to add a constraint, that says that Total has to be a sum of A & B.
Assuming the nodeset names are form/Total, form/B, etc., what is the
syntax??
constraint=("form/Total" = ....
I will be very grateful for your help.

Hi Jitka,
You should consider automatically calculating the total so the user
does not have to enter it.
If you want manual totaling, the below code should work in a constraint.
constraint="(/data/a + /data/b) eq /data/total"

Similar question so I'm adding here instead of starting a new thread.
My form is asking for household headcounts in divided by Adult_Male,
Adult_Female, and children in 3 age groupings. (total of 5 fields)
After these 5 questions I want an acknowledgement screen for accuracy
control
In the DISPLAY of this field, I would like it to calculate and display the
total of the 5 headcount questions,
Can I have an acknowledgement button AND a displayed calculation together?
Does the calculate function belong inside the output value in the label??
Ok, this is weird of me, but I'm going to post the answer to my own
question here, because I kept trying different things and got it to work.
In the Total field, include an output value in the label (display)
Is there a total of people
in this household?
the calculation goes in the binding:
and lastly, you have to use "trigger ref " in the body
I build forms with the odk build tool, but anyone who uses different tools
can probably apply this info to their format.
If an automatic calculation is used, would the syntax be calculate="(/data/a + /data/b)"? Thanks,
