I am trying to format the date in my survey into YYYYMMDD so that it shows up nicely in my instance_name setting field. I am currently trying to use the following formula to format the date in the calculation line of my date question :
format-date(${DATEOFSURVEY}, '%Y: %n: %e')
Connect keeps returning an error saying it is "invalid"
XLSForm is attached, any help is appreciated.
