Parent UDT passing parameter to Child UDT

I am having trouble passing a Parent UDT parameter into a child UDT.

The parent Parameter is {TwisterNumber}. It seems to break the pathway to the tag when I insert the Parent Parameter or even create a Child Parameter referencing the parent parameter. {Parent_TwisterNumber} = {TwisterNumber}


You cannot ever nest curly braces. This is one of the few cases where the tag() expression function is appropriate.


Thanks! That worked wonders.

Just pasting results here. In case this helps someone else in the future.
