The tag does not support writing

Hi,
I keep getting an error when writing to a tag parameter. It says The Tag does not support writing.
Is there any way to fix this

What kind of tag is it? Is it set to read-only mode, or read/write? Got a screenshot?

And which parameter are you writing to? Not all attributes can be directly written.

Hi,
I have attached a snippet of the parameter I want to change.

UDT parameters need to be changed using the system.tag.editTag function: https://docs.inductiveautomation.com/display/DOC79/system.tag.editTag

That is what I’m using. I have attached the script below.

You’re using system.tag.write, not system.tag.editTag
