Show your script. Use the \</\> code formatting button to preserve indents and syntax highlighting.

Consider using [system.tag.writeBlocking - Ignition User Manual 8.1 - Ignition Documentation](https://docs.inductiveautomation.com/display/DOC81/system.tag.writeBlocking) instead.

Consider using a document tag for the root, and a derived tag for each member you want t o modify (using `jsonGet` and `jsonSet`), which would expose each inner value as a distinct tag.

@paul-griffith on the same array some ID is null , thus why if i used document data type i will not know which element is it ? but if i used string array i will know from Array element no.  
what i am looking for is write only value on element array [1]!!
