Possible to Have a Question which is NOT Saved?

Support
1

Dear all,
In my form, I have an input widget where I want the enumerator to fill
in the interviewees ID. However to avoid Transcription errors, I want
the enumerator to confirm the ID by typing it again on the following
page and if the two ID's match then the enumerator can continue, else
a message tells the enumerator to go back and double check the entered
ID. Considering that I only want the second ID entered for comparison
and do not necessarily want to save two IDs which are exactly the same
in two different columns, how can I make the second input widget NOT
save its value, only be used to make comparisons?

Thanks in advance,
Tumaini

There is a tag that lets you specify the elements you
care to have submitted the rest are ignored (think of them as
intermediate value holders).

I am personally not clear how much of it is currently implemented in
collect, others can chime in. Here was the previous email thread on
the subject.

On ODK's Xform guidelines page in stricter syntax it talks about
http://opendatakit.org/help/form-design/guidelines/ in the "Stricter
Form Syntax - ODK Aggregate 1.0" item 3 talks about the submission
tag.

We should document how to do it better in the guidelines, so I filed an issue.
