I am using the iOS version and have (3) libraries. The first contains areas of my property. The second contains specific locations. The third contains jobs (per location). In my case, Lib2 is linked to Lib1. Lib3 is linked to Lib2.

Is there a way to capture the count of Lib3 items and display on the Lib2 field?

Добавить в библиотеку "lib2" поле JS с кодом:

entry().linksFrom('lib3','lib2').length;

//"lib3" - имя связанной библиотеки,

//"lib2" - имя поля в библиотеке "lib3", через которое осуществлена связь с "lib2".

Mmm,

Thank you for the response. When I enter as you suggested, I receive the following error...

TypeError: entry().linksFrom is not a function.

(In 'entry().linksFrom('zHSrv','ServDtl')',

'entry().linksFrom' is undefined)
