# How to make appear in mobile as in preview ?

Asked by Rajkumar on 2019-04-07

Hi OFT,
I have designed a survey for stem mapping. I have created ***sn*** for each stand(pole and tree) with like auto increment (**math:max(parent()/tree/id) + 1**). I need tag number (**tid**) for each tree(GBH>94). The tag number should appear for tree only. To do so I defined as like in **sn** here **math:max(parent()/tree/tid) + 1** (tid stands for tagged tree id). It looks perfect in preview mode. When I load it in collect mobile **sn** works. but **tid** does not.
one thing I have just put relevant when GBH>94 for **tid**. I guess this relevancy is preventing to return default value in collect mobile. But it behaves perfect in preview. My collect mobile and collect desktop are latest version.
plz suggest me the way my user do not need to enter data manually for **tid**(Tree Tag number). Here GBH stands for Girth in Breast height.

Thank you very much.
