red line around script...What does it mean???
I've made a rather basic game, which works fine except for one thing, the accuracy variable. It stays on 0 no matter what. I've got it set to:
When flag clicked
forever"
set (accuracy) to (shots hit)/(shots)
"

A script turns red when you make it divide by 0 
I think that's what you're doing...

Re: red line around script...What does it mean???
The red line means there's an impossible calculation in your script, such as trying to divide something by 0. If "shots" is set to 0, the script can't proceed because it can't divide by 0.
So, the solution would be to not perform that calculation while shots = 0. One way we could do that is by using this script:
That should fix the problem.
Does that help?

I'm taking a break from Scratch until 2.0 comes out. Any messages sent between then and now probably won't be read - sorry.

A script gets a red outline when any error of that kind happens methinks.
