Doesn't work with castable Malevolence

[Glorithan]

Here is my script section. My castable malevolence is on e but even when I right click, it will not cast.

FlaskDurationInit := []
;----------------------------------------------------------------------
; Set the duration of each flask, in ms, below. For example, if the
; flask in slot 3 has a duration of "Lasts 4.80 Seconds", then use:
; FlaskDurationInit[3] := 4800
;
; To disable a particular flask, set it's duration to 0
;
; Note: Delete the last line (["e"]), or set value to 0, if you don't use a buff skill
;----------------------------------------------------------------------
FlaskDurationInit[1] := 0
FlaskDurationInit[2] := 3500
FlaskDurationInit[3] := 6000
FlaskDurationInit[4] := 6200
FlaskDurationInit[5] := 8000
FlaskDurationInit[e] := 20000 ; I use Steelskin here
FlaskDurationInit[r] := 0 ; I use Molten Shell here

FlaskDuration := []
FlaskLastUsed := []
UseFlasks := false
HoldRightClick := false
LastRightClick := 0
