Hello, is there a way to include another tag’s value in a derived tag’s source tag path?  
I’ve tried tostr("[default]FolderName/" + {[.]MachineName} + “/parameter1”)

I don’t know if you can, but what are you trying to do? This seems like it could be an opportunity to use an [indirect binding](https://docs.inductiveautomation.com/display/DOC81/Indirect+Tag+Bindings+in+Vision) in the vision window.

I’m trying to set up a production line where different machines can be assigned to stations. In each station UDT, I have several derived tags that I want to be able to point to the corresponding OPC tags in the machine assigned to that station.

The right machine in each station UDT is determined via a query tag which checks for the information in a database. I’m wondering if I could somehow pull the information from this query tag into a derived tag path.

You can use `tag("[.]xxxxx") `, I think. I don’t use derived tags much though
