Null error?

I'm not super familiar with Stencyl so forgive me if I'm just being an idiot/misusing terms.

I downloaded and installed the Dialog Extension, copied the sample project's files/settings over, replaced some of its image and text files with my own, and ran the project. It's repeatedly giving me the same issue in the Flash player.

No clue what the issue is - there don't seem to be any name inconsistencies. Any help appreciated!

Looks like you're missing the animation displayed when waiting for user input to proceed the dialog. Check under the "Flow Scripts" extension in your data structures.

Thanks man, got it fixed (as well as many other errors in a similar line) and I think I finally understand the basics of how to use the extension. Great work, by the way.

It's now giving me a different error I have totally no idea what to do with - I know the dialog is responsible for its triggering but, having checked the source code the lines lead to, I don't know how to fix. Any ideas?

In the end, the problem was that there was a blank extension listed in the style.
