I may have wrong idea about the (gimp-image-get-layers) so please correct me

Try reading what I wrote about setting layer1 and layer2 using aref !

Sorry I forgot to mention, but I also tried this and also returned the same error: not enough arguments.
Kindly see below script. Thank you. Sorry I am still learning. 

(define (script-fu-gimpcompare3 num_layers image layers layer1 layer2)
  (let*(
        (num_layers (cad (gimp-image-get-layers image)))
        (layers (cadr (gimp-image-get-layers image)))
        (layer1 (aref layers 0))
        (layer2 (aref layers 1))
       )
    (plug-in-exchange RUN-NONINTERACTIVE image layer1 0 0 0 0 0 255 0 0 0)
    (plug-in-exchange RUN-NONINTERACTIVE image layer2 0 0 0 255 0 0 0 0 0)
    (gimp-layer-set-mode layer1 LAYER-MODE-MULTIPLY)
    (gimp-layer-set-mode layer2 LAYER-MODE-MULTIPLY)
    (gimp-displays-flush)
  )
)

(script-fu-register 
  "script-fu-gimpcompare3"
  "<Image>/Script-Fu/gimpcompare3"
  "blue red multiply"
  "Test"
  "Test"
  "2022"
  "RGB*"
  SF-IMAGE "Image" 0
)

EDIT:
OKAY I got it. I didnt need to put the variables for let inside the function. Thank you
