Paging not working

Hi

This is probably a stupid question, but I have created a Process Report and a Tempo Report from this.  Unfortunately, I cannot page the grid that results.  Can someone suggest what I am doing wrong?

Code below:

a!localVariables(
  local!pagingInfo: a!pagingInfo(
    startIndex: 1,
    batchSize: -1,
    sort: a!sortInfo(field: "c3", ascending: true())
  ),
  local!refreshCounter: 0,
  local!datasubset: a!refreshVariable(
    refreshOnVarChange: { local!refreshCounter },
    value: a!queryProcessAnalytics(report: cons!CMN_ALL_TASK_REPORT)
  ),
  a!sectionLayout(
    label: "",
    contents: {
      a!gridField(
        label: "",
        labelPosition: "COLLAPSED",
        data: local!datasubset,
        columns: {
          a!gridColumn(
            label: "Task Name",
            value: a!richTextDisplayField(
              value: {
                a!richTextItem(
                  text: {
                    fv!row.c5,
                    "  ",
                    a!richTextIcon(
                      icon: "external-link",
                      caption: "(Opens in New Window)",
                      size: "MEDIUM"
                    )
                  },
                  link: a!safeLink(
                    uri: rule!CMN_getTaskUrlByTaskId(taskId: fv!identifier)
                  ),
                  linkStyle: "STANDALONE"
                )
              }
            )
          ),
          a!gridColumn(
            label: "Status",
            value: a!richTextDisplayField(
              value: {
                a!richTextItem(
                  text: if(
                    fv!row.c1 = 0,
                    "Assigned",
                    if(
                      fv!row.c1 = 1,
                      "Accepted",
                      if(
                        fv!row.c1 = 5,
                        "Paused",
                        if(
                          fv!row.c1 = 8,
                          "Error",
                          "Unknown (code " & fv!row.c1 & ")"
                        )
                      )
                    )
                  )
                )
              }
            )
          ),
          a!gridColumn(
            label: "Assignee",
            value: a!richTextDisplayField(
              value: a!richTextItem(
                text: {
                  if(
                    find("Group:", fv!row.c4) <> 0,
                    a!richTextIcon(icon: "group"),
                    a!richTextImage(image: a!userImage(user: fv!row.c4))
                  ),
                  " ",
                  rule!APN_displayGroupOrUsername(groupOrUser: fv!row.c4)
                }
              )
            )
          ),
          a!gridColumn(
            label: "Assigned",
            sortField: "c3",
            value: a!richTextDisplayField(value: fv!row.c3)
          ),
          a!gridColumn(
            label: "Process Instance",
            value: a!richTextDisplayField(value: fv!row.c2)
          )
        },
        pagingSaveInto: local!pagingInfo
      )
    }
  )
)

Thanks
