# automatic numbering of objects only works in collect

Asked by Sabrina on 2020-02-03

Hi,  
The trees in my survey should be numbered automatically. The numbering should start at 100 and continue in steps of one (101,102,103). Therefore I created a number attribute with the following default value:  
__math:max(parent()/pb/baumnrneu)+101__ where "baumnummerneu" is the attribute and "pb" is the parent entity.  
In the preview the automatic numbering works. Not in collect mobile. Do you know why?

Thanks in advanved
