Error writing to " 'TAG'.value: Bad "

I am working my way through a tags and Productivity 1000 PLC.

I can read string tags but I cannot write to them them. I get the error attached.

I am able to read and write to Integer Data Type tags.

Is this an ignition issue or PLC issue? Thanks!

Pretty sure string lengths need to be even, as the underlying registers hold two characters apiece.

Thank you for the push in the correct direction. I was addressing the Item Path incorrectly.

In case anybody else needs good examples see the link below to the Ignition Manuel
