I can't figure out how to access part of a dataset I have within a UDT. I am creating a template and instead of having a bunch of template parameters to set/write to I figured I would put these parameters into a dataset within the UDT tag itself and then only have to bind the UDT to the template. Within my template I want to bind certain things to the UDT properties including within the dataset. I can get access to the dataset itself but can't figure out how to get access to say column 5 within the dataset. Here are screenshots of one instance of the UDT... ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/6/0/60cb7b50e235eacbada6a286808746bae68ac945.png) ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/6/6/6656d55a0441c8bb789408afb5b4e05f77a0ce37.png) Screenshot of start of the template with the template parameter UDTIn ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/2/e/2e0d6506632674f9ef63083fd57ab37fef0785f4.png) For example I want to bind the number of decimals for scaled min from a UDT parameter within UDTIn, PopupConfiguration. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/f/3/f3fa324f2747e404dae7ddb96fd93de7a177aac5.png) I tried doing a property binding to the UDTIn property but can't get within the PopupConfiguration dataset. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/1/1/11333c8c9f542a0fce91f748aabf86aafc9ad5d4.png) Do I have to do a different type of binding? My other thought was just having the tag name be a template parameter and seems like I can get to parts of the dataset that way... ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/d/4/d42c03186ba825712d6b6ecf7688117c47ac0223.png) Any way to do it using the UDT property? ---

General tag configuration properties cannot use expressions that reference tag values or other property values. They can only reference UDT parameters (including the built-in UDT params). Tag **alarm** properties **can** reference other tag values, but are only updated on alarm events--they are **not** general subscriptions. The only general use of tag references, with ordinary change tracking causing refreshes, is within the expression of an expression tag. Full stop. What you **can** do is **write** to these tag properties from scripts. ---

Scratch that...doesnt seem to work either ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/c/4/c446bce5cc28e3d6b045186abe2cb79264eaae95.png) ---

If I created a template parameter dataset within the template where everytime the template instance was opened the template parameter dataset was populated from the tag dataset itself would I be able to access that from within the template? ---

Not sure how you intend to populate it. Are you not using a tag path parameter to your template to drive indirect binding within the template? If not, you are screwing up. If you **are** using a tag path, then you can indirect bind to any nested tag and/or tag property within the UDT. In other words, it seems you are trying to go through your [expletive] to get to your elbow, when you could just touch your elbow. 🤷‍♂️ (If you are trying to display all of this stuff in a table, take a look at the `tags()` function in my Integration Toolkit.) ---

Right. That was my next attempt. Do an indirect tag binding with the template parameter coming in as a string to complete the tag path. I do seem to be able to get to the parameters that way.
