Invalid index (4) for list: valid range is 1...3

I have fixed the above issue.

ireneb: Would you mind explaining what you did to fix this error? I'm hitting something similar at the moment. Thanks!

The invalid index error is generated with square-bracket indexing such as ri!myVar[15], when the index requested is higher than the count of items in the variable.  Feel free to start a new thread with your details and we'll be happy to take a look.  

In line 24 above:

 } + { tointeger(property(local!totalHours,"totalHours",null)[fv!index]) }

This error would be thrown due to "[fv!index]" if the local!totalHours variable has less items than the ri!casualWorkSchedule variable.  Changing the line to use fn!index() as below would resolve the error message.

} + { tointeger(index(property(local!totalHours,"totalHours",null),fv!index,null)) }

Hi Robin

I don't really remember what I did to fix this but below is the code that works:

load(
  if(
    rule!CMN_checkNullOrEmpty(ri!casualWorkSchedule),
    tostring({}),
    with(
      local!weeks: index(ri!casualWorkSchedule, "weeks", {}),
      local!weekEndingDate: (todate(local!weeks) + 4),
      local!totalHours: a!forEach(
        items: rule!CAT_getUniqueElements(local!weekEndingDate),
        expression: rule!CAT_getTotalHoursWorkedByFanWeekEndingDate(
          fan: ri!selectedCasual,
          weekEndingDate: fv!item
        )
      ),
      local!proposedHours: a!flatten(
        a!forEach(
          items: ri!casualWorkSchedule,
          expression: 'type!{urn:com:appian:types}CAT_ACADEMIC_WORKLOAD'(
            week: index(local!weeks, fv!index, null),
            totalHours: rule!CAT_calculateProposedHoursFromCasualWorkSchedule(tempWorkSchedule: fv!item)
          )
        )
      ),
      local!sumHours: a!flatten(
        a!forEach(
          items: ri!casualWorkSchedule,
          expression: 'type!{urn:com:appian:types}CAT_ACADEMIC_WORKLOAD'(
            week: index(local!weeks, fv!index, null),
            totalHours: sum(
              {
                index(
                  {
                    todecimal(
                      property(local!proposedHours, "totalHours", null)
                    )
                  },
                  fv!index,
                  null
                ),
                index(
                  {
                    todecimal(
                      property(local!totalHours, "totalHours", null)
                    )
                  },
                  fv!index,
                  null
                ),

              }
            )
          )
        )
      ),
      if(
        and(
          rule!CMN_checkNullOrEmpty(local!weekEndingDate),
          rule!CMN_checkNullOrEmpty(local!totalHours),
          rule!CMN_checkNullOrEmpty(local!proposedHours)
        ),
        {},
        {
          a!sectionLayout(
            label: "",
            contents: {
              a!forEach(
                items: local!sumHours,
                expression: {
                  if(
                    fv!item.totalHours > cons!CAT_VALID_WORK_HOURS,
                    a!richTextDisplayField(
                      labelPosition: "COLLAPSED",
                      value: {
                        a!richTextItem(
                          text: "This casual will be working " & fv!item.totalHours & " hours for the week of " & fv!item.week & " across this and/or other topics.  Please consult with the topic or course coordinator or Dean (P&R) before submitting.  Refer to the Casual Workload report.",
                          color: "#F06A28"
                        )
                      }
                    ),
                    {}
                  )
                }
              )
            }
          )
        }
      )
    )
  )
)

Hope this helps.

Thanks
