Just thought I'd mention that I just now added a "quick-parser" which detects any errors in your data fields and highlights them red! Very simple to do given that I was already running the data through the script engine all at once - this time I just run some of it through!
The quick-parser also lets you hover over a field and view its value; haven't tested it with actual templatized items, mainly because I haven't implemented those yet, but I imagine it would look something like this: [10, 20, 30, 40, 50] for a simple 5-level progression
