Hi all!
I've checked the forum in vain, I'm still not happy.
I need to collect data for children aged 2mo - 5 yrs at inclusion. If the exact date of birth is unknown we mark 09-09-2099 and write the approximate age in months.
I tried the enclosed example. I've checked the date() and decimal-date() functions but they didn't work.
What's wrong with my formula? How to proceed?
Many thanks.

Serge, you could also add a Yes/no Question "Do you know DOB" and then if the answer is "NO" just don't show the enter date prompt...
1 -> The default date of birth works on enketo but not on odk collect
2 -> The date of birth '09/09/2099' is considered as an illegal value
3 -> Naturally the relevant field for the age does not work
4 -> The age is not automatically computed.

Yeah. That's a great idea.
So I imagine everything is now solved.
This forum is really great.
Thanks a lot.

Hi Serge,
When troubleshooting, break down the problem into smaller chunks. I
find that, plus a combination of debug variables using calculates and
outputs helps a lot. I found five problems with your form.
Attached is a form that solves the above issues. Many of these issues
could have been fixed by going through the resources at
http://xlsform.opendatakit.org and
http://opendatakit.org/help/form-design/binding. I encourage you to
look through the above links for further guidance.
As to things that don't work with enketo, ask on
https://groups.google.com/forum/#!forum/enketo-users.

Wonderfull. Several points have been solved.
But the legal value "2099-09-09" still doesn't work. This works properly on
enketo but not with ODK collect.
A widget is displayed and when I enter "09 -- sep -- 2099" it returns the
error message.
Is it possible to force a simple date entry "2099-09-09" in the place of
the widget, this would be simpler.
Many thanks.
Serge
Hi Serge,
When troubleshooting, break down the problem into smaller chunks. I
find that, plus a combination of debug variables using calculates and
outputs helps a lot. I found five problems with your form.
- The date format you use is not correct. "2014-12-31" is the correct
format.- When you subtract days from dates, wrap the operation like so:
"date(${date_obs} - 60)"- Division is done with div, not /. For example, "10 div 2" will give you
- Defaults cannot contain variables or commands. If you want get
dynamic 'default', use the calculation column.- Age should probably be an integer since div will give you an overly
precise number (e.g, 12.21321412512)Attached is a form that solves the above issues. Many of these issues
could have been fixed by going through the resources at
http://xlsform.opendatakit.org and

look through the above links for further guidance.As to things that don't work with enketo, ask on
