Hi there im new around here, this is my first post! I was running through the official tutorials and installed Jet's Skill Self Effects script. Although i havent even tried to implement any features of the script, when i test my project it crashes with an error every time i attack

Error: Script 'skill self effects' line 37: NoMethodError occurred

           Undefined method '[]' for nil:NilClass

Here is the text copied from the script:

#===============================================================================

# Skill Self Effects

# By Jet10985 (Jet)

# Requested by Touchfuzzy

#===============================================================================

# This script will allow you to specify a skill's effects tot arget the user

# instead of the target, on skills that don't already effect the user.

# This script has: 0 customization options.

#===============================================================================

# Overwritten Methods:

# None

=begin

To specify the effects, use this notetag in the skill's notebox:

 

<self effect: 1>

or

<self effect: 1, 2, 3> to specify more than 1 effect

--------------------------------------------------------------------------------

Use of this script could be as the following.

 

You make a "Berserk Strike" skill, which does 200% damage to an enemy.

You make the 2nd effect "Defense Down 50%" and want it applied to the user.

You'd use this notetag: <self effect: 2>
