Hi, all. Having some odd trouble. I'm making a tonerow abstraction for myself, and have run into an issue. For some reason, the data just won't go into the array. I have a feeling the reason is staring right at my face, and it's something stupid I'm ignoring. Can anyone see what's going on?

The main things are that message boxes use the format $1 instead of $f1 (which only the expr family uses). You are also not sending to to an array with an abstraction-specific name. Heres a version of your abstraction with what I believe you want to accomplish.
