Nested paths on data type expressions?

Ignition

I created a data type in which I will have a parameter to indicate an alarm condition. I want to use it with an indirect reference, so that that the Index will be used in the tag path on each instance as follows:

tag{“Tags/Ramp/Ramp”+{Index))>250

This produces an error in the instance “Nested paths not allowed”
Error configuring tag for execution. Error:
Scan Error: Nested paths not allowed. (Line 1 , Char 25)

Is there another way to do this?

Replace your curly braces with regular parenthesis.

Thanks for your replies. I fixed the problem; the function tag() requires parens and the parameter Index requires curly braces.

{[edge]AIT_001/H_Alarm}

I am getting the error, nested path not allowed.
How I can use the indirect tag as AIT_001 in the expression?

Create a custom property to retrieve the indirect tag. Use that property at that spot in your expression.
