Hi All, I have UTD for which I have a custom property ‘asset\_id’. I then configured an alarm on a tag withing the UDT which also has a custom property ‘asset\_id’ which I want bound to the UDT’s ‘asset\_id’. Is there a way to do this? In trying to solve my issue in another way, I found that the expression language does not function on tags or tag custom properties the same as if they were on say a vision component. For instance, if I try create a tag within my UDT who’s value is `split({PathToParentFolder}, "/")[3, 'parts']` it doesn’t work as expected. ---

Can you just try putting {asset\_id} there? ---

Okay can you create one memory expression tag linked to the UDTs property and have alarms property referring to that expression tag? ---

Tried that too - Like I say, I think expressions don’t work exactly like they do in Vision - not sure if this is intended or not ---

Try `{[.].asset_id}`: ![Custom Prop from Alarm Associated Data](https://us1.discourse-cdn.com/inductiveautomation/original/3X/9/a/9acd3a803f23b53479f12a3d36300b572b01d5b5.gif) ---

I thought that worked for me but having tested more it doesn’t. @kcollins, how does one create those videos so I can show my configuration? ---

If you’re on Windows, ShareX is FOSS and can screen record to GIF. On MacOS, I like Kap (also FOSS), but others may have more informed opinions. On Linux, I dunno, use `ffmpeg` or something 😆 ---

Hi Guys, Sorry, wasn’t able to get to this until now. As you can see, the ‘label’ alarm property isn’t coming through to the email notification. @kcollins UDT Alarm Tag Configuration: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/b/c/bca0cd28761a6de5a8c56ac0f4e4fbb82809f90e.png) UDT Instance: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/d/a/da8a3f0a5862fbe39a2805a3daced14f04f4a2b9.png) Alarm Pipeline: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/0/e/0e052ff3e45f9776db43b05a054140561d07d38e.png) Email Notification: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/5/a/5a25e7970fcabeb16d4b39da7d4633822c0e8c84.png) ---

Submitted a ticket to IA support. Keaton Elliott helped me realize the alarm ‘Label’ property and ‘asset\_name’ custom property needs to be expression syntax. Like: Label property: `{asset_name} + ' Error'` asset\_name custom property: `{[.].asset_name} + '_p' + {InstanceName}` Now works as expected! ---

Hello everyone! I'm facing a similar issue. I would like to access a Custom Property value using an Expression Tag. I've tried `{asset_name} ` and `{[.].asset_name}` to get "CustomTest" text ![java_V7LEVqGGUD](https://us1.discourse-cdn.com/inductiveautomation/original/3X/e/c/eca8041154041d0be68f580fc9473ffdfff7e903.gif) ---

Nevermind, using `{[.]Test.asset_name}` worked !
