Accessed None trying to read property TextBlock - Dialogue Builder

Hello!

Two days ago I bought the Dialogue Builder plugin:
https://www.unrealengine.com/marketplace/en-US/product/dialogue-builder

And I used this tutorial for the implementation: https://www.youtube.com/watch?v=4w8NpR1wgOU&t=2134s

Everything went smooth until 40 minutes of the video.
Unfortunately when entering a trigger box game plays the sound of the dialogue but it’s not displaying a text. That’s because of this error:

As far as I know I did eveyrything like in the video and it’s showing an error right here:

The TextBlock is checked as variable

Has anyone have any suggestions about it?
At first I thought that’s because a text variable has an eye closed next to it and it can’t be changed but reading about it made me think that’s irrelevant.

If you need any additional screens please let me know.

I followed the upper video step by step and audio works but the text is not changing like I said.

I know this error well unfortunately. It usually means there is a breakdown in BP communication or there is a null variable found. The question is where the breakdown is.

I don’t have time to watch the whole tutorial, but I would try putting in print strings along the way to see at what point the text data is missing.

The data is not getting where it needs to go. But tracking down why is another story. That’s why you might have to start over, but do print strings along the way and find out at what point does the lack of access occur.

The good news is it is definitely 100% fixable. But you need to know where the breakdown is.

Is there a BP interface involved with this? What role is the struct serving? Is the text data coming from an array?

Here’s one tutorial that might help.

Also, if you can’t get it to work, here is an alternative system you could look at:
