7800basic incgraphic/png question

[Bradsco]

First thanks to RevEng for everything that has gone into 7800basic. I've been a developer for years, but to have this as a stepping stone into 7800 development is fantastic. I'm working through the samples, and compiling/testing are fine.

 

The problem occurs when I try to modify the content of a sprite. In the simple example, even if I just duplicate face1.png and rename it (updating the source file as well) I get an Unresolved Symbol List compile error. In a case like this where I haven't edited the content of the sprite, I figured it should work. What else am I missing?

And I'll answer my own question.... make sure you update the subsequent references to the sprite in the code as well
