I try to retrieving a sample point as default value of coordinate attribute.I used the demo sample points.
my retrieving expression in IDM Expression Language is idm:samplingPointCoordinate(01,01).
The coordinate system is also EPSG:4326 for my Survey.
in the preview I got empty form without default values.
my collect version is 3.8.19.
let me know if I miss any detail Thanks,

Hi,
the expression is "almost" correct... the only thing to change is that the parameters must be text values, like this:
idm:samplingPointCoordinate('01','01')
In this way the retrieved coordinate will always be the one corresponding to level_1='01' and level_2='01', is it the behaviour you are expecting? It will be more useful to have a dynamic lookup of that coordinate, specifying a path to an attribute instead of a constant value.
Many thanks,

now its work..! :) you right,that way is much more flexible. Now for a test I change it to idm:samplingPointCoordinate(concat('0',idm:position())) and work perfectly. Thanks.
