How do I run C3 code using JSON comparison?

Hello,

I bought this really cool dialogue system for Construct 3.

What I am trying to do is run a C3 block of code when certain line executed in the dialogue system.

Basically, I am trying to execute a C3 block of code once the last line array of "dialogue" is shown using the "JSON compare value" attempting to compare it's "id" within the "dialogue" nested array. I looked at the JSON documentation online on how to execute this. Unfortunately, it is not working. Is there something I am doing wrong or I am missing?

JSON file code:

	{
	"scene": [
		{
			"id": 0,
			"dialogue": [
				{
					"id": 0,
					"char": "npc0",
					"voice": "",
					"line": "This is scene 0."
				},
				{
					"id": 1,
					"char": "npc0",
					"voice": "",
					"line": "Here is a 2nd line."
				},
				{
					"id": 2,
					"char": "npc0",
					"voice": "",
					"line": "Here is a 3nd line."
				}
			]
		}
	]
}

C3 code block:

Any Help is appreciated.

Thank you for your response dop2000.

I understand it's hard to give an accurate solution without seeing the full dialogue engine.

However, your response and the C3 attachment has gotten close to a potential solution.

Thank you.
