I don't know how to create a formula to apply a discount using a promo code to the price. However, when a student types the promo code and it matches an entry in the SharePoint list, a discount will be applied in PowerApps.
@Ali_SZ_365, thank you for sending this; it has been a lot of help. Also, where does 'TotalCartPrice' come from?
Before we start with that, I have a bit of an issue summing up the total price from the gallery to the label. 😞
"$"&Sum(Gallery4_2.AllItems,'Dragon Tickets')
Still error: Sum(Gallery4_2, yourPriceColumn)
Other thing:
@Ali_SZ_365, i just added 'varDiscount' to the 'PBiS Discount' label, and it is now working.
Then, what about putting the 'Shopping Cart - Dragon Tickets:' label into some formula?
Correct??
