Mr Mo SBABS Issue

[Kingcobrasaurus]

Whenever my character uses a ranged skill I get this error:

What does this mean? Does anyone know how to fix this?
EDIT: Also, when my character tries to use a non-ranged skill, it doesn't do anything. i don't get what's happening.

EDIT 2: Well, I've tried fixing this problem with no avail, it seems that there's a conflict with another script I'm using. so iugnore this. I'm notgoing to use mr mo's SBABS.

What is on line 1434 of the script?

It's

enemies = get_all_range(@actor.event, RANGE_SKILLS[skill.id][0]

Now, I don't understand a thing of RGSS, so I have no idea what this is.
