NetLogo - Sandpile - Error

I am chasing my tail with this piece if code. Having rectified one error (with the help of stakoverflow) i now get another. The error reports "TASK expected 1 input, a reporter or task command" and highlights the word "task". I am not sure if it to do with the brackets?

;; The density of patches to be set with a random value is set using variable init-errors on interface.
;; Every patch uses a task which reports a random value.
;; The random value is set using variable error-count on interface
to setup-random
   ask patches [
     if (random-float 100.0) < init-errors
        [ setup task ] [ random error-count ]

I think you just want setup task [ random error-count ], so that you're passing the reporter block [ random error-count ] to task. So the whole thing would look like:

to setup-random
   ask patches [
     if (random-float 100.0) < init-errors
        [ setup task [ random error-count ] ]

The above assumed that setup was a procedure runnable by patches. If this is actually just a modification of the sandpile model in the models library, then you probably want:

to setup-random
   setup task [
     ifelse-value (random-float 100.0 < init-errors) [
       random error-count
     ] [
       0 ;; Or whatever you want your non-"error" patches to get.
     ]
   ]
