*WARNING* Form 'Form', field 'check': Bad value "check5". Must be a list.

Please provide complete examples - you seem to follow the pattern of your predecessor saurabh96 in not providing a full code example but snippets of code. Often that's not enough to show the problem.

You talk in the subject line about cyclic fields, but this is not using a cyclic field. It's using a list box.

Anyway, the problem is two-fold:

1. Your callback is using "=" instead of "==". You're trying to check equality, not assign the value
2. The ->value of a listbox (because it can have multiple items selected) is a list not a string

Changing the condition in the callback function to:

if(form->check->value == list("check5") then

fixes the problem.

By a full example, I mean something like this - note I've added the extra code to allow the code to be run (this is after I made the fix). You're far more likely to get help if you minimise the amount of work somebody has to do when responding here - we're all doing this in our own time (including the Cadence folks like me - it's not part of my role at Cadence to respond here). If it involves a lot of repeated effort, you're likely to get ignored...

; indented the code to make it readable
check=hiCreateListBoxField(
  ?name 'check
  ?multipleSelect t
  ?callback "back(hiGetCurrentForm())"
  ; the list of choices was missing
  ?choices list("check1" "check2" "check3" "check4" "check5")
)

procedure(back(form)

  ; fixed the condition
  if(form->check->value == list("check5") then

    op = outfile("./ffile" "w")
    fprintf(op "success { \n")

    close(op)
    (view "ffile")
  )

)

; added a small form around the field to show the problem
hiDisplayForm(
  hiCreateLayoutForm(
    'forum114
    "Forum114"
    hiCreateFormLayout(
      'lay
      ?items list(check)
    )
  )
)

Andrew, am sorry for unclear quotations-
thanks it was clear.
i have write below code in which am trying that if i select all check together i get output like check1 success
check 2 success.

check 3 success.

check 4 success.

check 5 success.

check=hiCreateListBoxField(
?name 'check
?multipleSelect t
?callback "back(hiGetCurrentForm())"
; the list of choices was missing
?choices list("check1" "check2" "check3" "check4" "check5")
)

procedure(back(form)

; fixed the condition

op = outfile("./ffile" "w")
fprintf(op "%s success \n" form->check->value)

close(op)
(view "ffile")
)

; added a small form around the field to show the problem
hiDisplayForm(
hiCreateLayoutForm(
'forum114
"Forum114"
hiCreateFormLayout(
'lay
?items list(check)
)
)
)

if am selecting all rules and running ,error prompt is- *Error* fprintf/sprintf: format spec. incompatible with data - "Format is '%s success \n', argument #1 is (\"check1\")"

As I explained before:

Andrew Beckett said:

You are trying to print a string (with %s) but you are passing a list (as the error message states). Simplistically you could just change the %s to %L.
