This can be possible only if you store tag as number from descending to ascending, then call get tags store in variable using reverse list block, then call it will show latest data first.

Hi @Still-learning,

Wana ask what if the list is empty or nothing, what is the workaround for the sortdescend blocks ya?
Thanks

then use one condition like if the list is empty through alert else run the logic

when web go text
if length of the list call web1 JSON Text Decode json Text(get response content) = create empty list
then show notifier alert
else call Listnoinja SortDesending list call web1 JSONTextDecode json text(get rspon COnt)

Oh sorry i misspelled it. Insted of create empty list in the comparison block use 0 (zero)

Length will return integer and it cannot be compared with yailist.

  1. If you use length then compare with 0
  2. If you remove the length let it be the same structure

still the same, or i did it wrongly?
