Dont know why it not work
UpdateIf(Table, Seq>ThisItem.Seq &&Id= ThisItem.Id, {
Seq:Seq-1
});
And I had trying to do
UpdateIf(Table, Seq>ThisItem.Seq &&, {
Seq:Seq-1
});
It work except same id item not update
Using the Same filter to Set a table can find the value i need
Even I hardcode all value it still not work
