Issue with Summary Range formatting

 ->formatStateUsing(function ($state) {
  return $state / 100;
})

 ->formatStateUsing(function ($state) {
  return $state / 100;
})

 ->formatStateUsing(function ($state) {
  return $state / 100;
})

 ->formatStateUsing(function ($state) {
  return $state / 100;
})

wont work because

Unsupported operand types: array / int

Unsupported operand types: array / int

Unsupported operand types: array / int

Unsupported operand types: array / int
dd state:

array:2 [▼ // ...
  0 => 100
  1 => 400
]

array:2 [▼ // ...
  0 => 100
  1 => 400
]

array:2 [▼ // ...
  0 => 100
  1 => 400
]

array:2 [▼ // ...
  0 => 100
  1 => 400
]

ok, so I do

->formatStateUsing(function ($state) {
  return  $state[0] / 100 . ' - ' . $state[1] / 100;
})

->formatStateUsing(function ($state) {
  return  $state[0] / 100 . ' - ' . $state[1] / 100;
})

->formatStateUsing(function ($state) {
  return  $state[0] / 100 . ' - ' . $state[1] / 100;
})

->formatStateUsing(function ($state) {
  return  $state[0] / 100 . ' - ' . $state[1] / 100;
})

it just shows

1

1 and nothing else

how do I format this then? (want 1-4)

Solution

you need to return an array with each number
