I want to calculate this equation

λ=(∑▒〖λ_i [1-((I_i+V_i)/I_c)]〗)/(∑▒〖[1-((I_i+V_i)/I_c)]〗)

Where
IDL> help, image
Image FLOAT = Array [500, 1000, 20, 4]
,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,
I=image (*,*,*, 0)
V=image (*,*,*, 3)
,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,
I write idl program as
close, 1
restore,file='D:\Science\image.sav’
ic=mean(reform(image[*,*,0:6,0]))
nx=500
ny=1000
for i=0,nx-1 Do begin
for j=0,ny-1 Do begin
I1=image[i:nx-1,j:ny-1,*,0]
V1=image[i:nx-1,j:ny-1,*,3]
wave1=fltarr(TOTAL(wave*(1-((I1+V1)/IC)),/cumulative))
wave2=fltarr(TOTAL(1-((I1+V1)/IC),/cumulative))
Pwave=fltarr(wave1/wave2)
endfor
endfor
tvscl,I1
end

the problem is no image are appears, black screen only
please help
