Scripting-noob has questions

Hi guys,

I'm new to this forum (and scripting in general) but decided to take the plunge and learn. I'm trying to write a script that randomly scales objects between two values, using the very basic Maxscript-knowledge I have right now.

I run into two problems:
- When the rollout opens, I'd like the default values to be set to 0.9 for 'min' and 1.1 for 'max', but can't get it to work.
- When I use the current rollout, and don't change the values, the scaling goes hopelessly wrong. Even though the spinners say 0.9 by default, it seems to be using '0.0' as a default
- Is there a way to use three digits after the komma?

Thanks a lot, I'll post the code below.
