Writing Scripts in MEGUI also AVSPMod

[Sagitarius1948]

I have AVSPMod and I can write scripts in it. However when I open up MEGUI's script writer I get an error message. I obviously am doing something wrong in my script writing in MEGUI. Any help would be apprediated.
This is my script:
------------------------------------------------------------------
I tried this script below in MEGUI hoping that it would accept FluxSmooth:
:
:
Import("E:\A Matter of Life and Death.avs")
#deinterlace
#crop
#resize
LoadPlugin("C:\AVI Synth LoadEX\LoadPluginEx.dll")
LoadPlugin("C:\MEGUI\tools\avisynth_plugin\FluxSmooth.dll")
LoadPlugin("C:\MEGUI\tools\avisynth_plugin\UnDot.dll")
Undot() # Minimal Noise
FluxSmooth()

I got the error message:
X AVISynth script error.
Script Error there is no function named "FluxSmooth"

I then tried the same script in AVSPMod by cut and paste and got the same error message.
However if I write the message myself in AVSPMod, it accepts it well.

So there is something in my writing of AVISynth where I am going wrong but what?
