Hello,

I was trying to bind the InstanceName of an UDT to the DisplayPath of an Alarm in the UDT. When I do it strictly by binding the UDT Parameter it works fine. If I type in the Display Path the variables that I want, it works fine. But when I try and create an expression with a UDT Parameter, it does not work and I get a red x on the Alarm in the Instances?

Thanks,  
Mike

Hi,

I had the same problem and I’ve resolved it using the single quotes in the expression: [https://inductiveautomation.com/forum/viewtopic.php?f=72&t=15297](https://inductiveautomation.com/forum/viewtopic.php?f=72&t=15297)
