I am trying to use the system.tag.editTag function to modify the OPC path when a button is pressed when this action is done I get an error in published environment and does not work. Any suggestions or corrections?

system.tag.editTag(tagPath="[default]Motor\_FVNR\_HOA\_0", attributes={“OPCItemPath”:"[LOD\_W\_CRUSH\_TCC]S1\_Area\_Cntl.Pomace\_Incline2.PV\_HOA"})

Without being able to see the actual error, I’m guessing [Client Permissions](https://docs.inductiveautomation.com/display/DOC79/Project+Properties#ProjectProperties-ClientPermissions) located in the Project’s Properties is preventing you from editing your tags on the Client. Specifically, **Tag Editing**

Enable Tag Editing, and the clients should be able to run your script.

Just a heads up, this will also work, assuming proper permissions and stuff

```auto
system.tag.write("[default]Motor_FVNR_HOA_0.OPCItemPath","[LOD_W_CRUSH_TCC]S1_Area_Cntl.Pomace_Incline2.PV_HOA")

```

Client permissions were the issue, Thank you for your time!
