Hello! 
I don’t have a problem, but I found a bug where ${} doesn’t display variables correctly. These are only edge cases I’ve found while playing around, so I don’t think many people have experienced this at all. I’ve tested this on CSIDE and Dashingdon.
Opposed Stats:
*temp xp_percent round(xp/100)
*temp lvl 9
*temp blank ""
*temp name "name"
*stat_chart
percent hp $!!{name} (LvL ${level} $!{class})
opposed_pair xp_percent
EXP
Until LvL ${lvl+1}
${blank}
*stat_chart
percent xp_percent Until LvL ${lvl+1}
It will display like this:
This only appears on the right side of the opposed stat.
I found a workaround just by doing an *if/else. (Luckily I don’t need many *ifs since you can only level up once in my game.)
Multiple Choices:
*temp him "her"
*choice reaction answer
#"I like ${him} very much...
#...we have to go save ${him}!"
*finish
#...we have to stay here."
*finish
#"I don't like ${him} very much...
#...we have to go save ${him}!"
*finish
#...we have to stay here."
*finish
It will display like this:
It displays correctly on the first set of options, but not on the second (and succeeding?) set of options.
Again, there’s a workaround with *if/else, but that’s a little trickier to code with multiple options.
Also, is there a way to change the text after “Select a”? I’ve tried using strings and variables, but it doesn’t work. If not, I can live with it. It’s just annoying and it only limits the use of multiple choices.
Side Note:
I know it’s not necessary to include how much remaining % EXP you need exactly, but the blue bar looks much better than another red bar.
Also, a neat little trick I’ve discovered: that “${blank}” there adds a slightly bigger space between the stat bars.
Another thing about the opposed stats: I also wanted to show a symbol that appears beside the stat if it’s being buffed/modified, but that doesn’t work. The *if workaround also works here but I figured it was clutter anyway.
You know, just spitballing why you’d ever want to put variables on opposed stats. It’s fun playing around with the stats screen (Am I the only one? 
)
I know it’s not used much, but still.
