Migrating a discounted cart subtotal script
Two scripts can look identical here and mean opposite things. One measures what its own earlier lines left behind; the other measures what somebody else’s discount left behind, and only the second is out of anyone’s hands.
Limite di ShopifyIt subtracted the shopper’s discount code from the subtotal first, then compared what was left against its threshold.

- Nell'admin di Shopify apri Stackable, poi Strumenti, poi Recupero Script.
- Incollalo lì, leggi cosa dichiara di costruire lo strumento e confrontalo con le impostazioni di questa pagina.
Recupero Script è nel piano Pro. Non viene pubblicato nulla finché non dichiari quanto scontava il vecchio Script e le due cifre non coincidono al centesimo.

Your Script measured its threshold against a subtotal that another discount had already reduced. Discounts at checkout all run at the same moment and cannot see each other's work, so we only ever see the original amounts.
