Hi It seems that you are using older version of Appian (As you have used a!gridTextColumn() in your modified code).

Please try with below code. It should work.

load(
  local!pagingInfo: a!pagingInfo(
    startIndex: 1,
    batchSize: 10
  ),
  local!rule1: {
    "ABC",
    "CDE",
    "GHI",
    "JKL",
    
  },
  local!rule2: {
    "ABC",
    "DEF",
    "ABC",
    "DEF",
    "GHI",
    "ABC"
  },
  local!data: a!forEach(
    items: local!rule1,
    expression: {
      value: fv!item,
      count: count(
        wherecontains(
          fv!item,
          local!rule2
        )
      )
    }
  ),
  with(
    local!dataSubSet: todatasubset(
      local!data,
      local!pagingInfo
    ),
    a!gridField(
      label: "",
      totalCount: local!dataSubSet.totalCount,
      columns: {
        a!gridTextColumn(
          label: "Value",
          data: index(
            local!dataSubSet.data,
            "value",
            {}
          )
        ),
        a!gridTextColumn(
          label: "Count",
          data: index(
            local!dataSubSet.data,
            "count",
            {}
          )
        )
      },
      value: local!pagingInfo,
      saveInto: local!pagingInfo
    )
  )
)

I modified the code as below but grid is showing empty.

load(
local!pagingInfo: a!pagingInfo(startIndex: 1, batchSize: 10),
local!rule1: {
"ABC",
"CDE",
"GHI",
"JKL",

},
local!rule2: {
"ABC",
"DEF",
"ABC",
"DEF",
"GHI",
"ABC"
},
local!data: a!forEach(
items: local!rule1,
expression: {
value: fv!item,
count: count(
wherecontains(
fv!item,
local!rule2
)
)
}
),
a!gridField(
label: "",
totalCount: 10,
columns: {
a!gridTextColumn(
label: "Value",
value: fv!row.value
),
a!gridTextColumn(
label: "Count",
value: fv!row.count
)
},
value: local!pagingInfo,
saveInto: local!pagingInfo
)
)

Value	Count
No items available
