script to get __ComponentsJson of a summary key

[Rosa Prod]

Hi,

 

Is it possible to get The count and the name of the componementsJson in a summary key ?

I've tried a script with GetRfiled(h,''Summary Key','__ComponentsJson'); but it return to me all the informations. I just need the count and name. 

In fact i try to make a script that give me the name and the count of projectors on selected hanging position and write it into the EntEquipUniversal of the hanging position.

 

Thanks for answers and have a nice day !

 

And sorry for my bad English 🤦
