请问为什么这个鼠标脚本会报错？

#Basic Mouse System v2.7h
#----------#
#Features: Provides a series of functions to find the current x, y position of
#           the mouse and whether it is being clicked or not (left or right click)
#
#Usage:   Script calls:
#           Mouse.pos?   - returns the x, y position as an array
#           Mouse.lclick?(repeat) - returns if left click is achieved
#                                   repeat = true for repeated checks
#           Mouse.rclick?(repeat) - same as above for right click
#           Mouse.within?(rect) - passes a Rect through to check if cursor
#                                 is within it, returns true if so
#
#         Events:
#          The following are placed in the name of an event:
#          &&  -  event can be triggered from afar by mouse click
#          I:# -  where # is the icon_index to change the cursor on hover
#  
#         Example: I:262
