SOLVED Discount Q method for V4 working on V5?

It weird Show Message display just as I type in.

{PRICE} {ORDER STATE:DStatus}

{PRICE} and {ORDER STATE:X} are valid tag.

Update:

Constraint {ORDER STATE:DStatus}, {ITEM TAG:Discount} don’t work too. I have {ITEM TAG:Discount} in Order Add To Ticket Rule to change DStatus to Discount and it work in new order add to ticket.

This is not working (Try to stop discount if order state DStatus is not Discount). Actually, it stop because it never match (Null will never contain Discount, rule will never be fired)

This is working (Add Order State Discount to DStatus)

@kendash or @QMcKay if you still have this setup could you confirm this please?
