Error in GetColor

Hi Ankalua, can you help me?

I got error in function getColor   The Script is:

usePreviousSnap(false)
if exists(Pattern(vName), 1) then

r1a, g1a, b1a = getColor(Pattern(vName))

else

return false

end



Sometimes it is working, sometimes it get error code:
"
Runtime error: com.appautomatic.ankalua.f:Can't find P(../../custom/ffbe/image/nox1/battle/btn_repeat.png) S: 0.9
stack traceback:
[C]: in function 'getColor'
?: in function 'getColor'
"

there is the image there because sometimes it working properly

thanks
