Hi everyone,
I'm a beginner on this platform. Currently, I'm working on a medicine expiration alert application. When a user selects medicine details from a list, the information will be passed to a medicine details page. On this page, there will be a dropdown widget (1 month, 1 week, 3 days) that allows the user to choose when they want to receive a reminder. I have the expiration date stored in my database.
For example, if the expiration date is 24/06/2024 and the user chooses "1 week" from the dropdown widget, they will receive an alert 1 week before the expiration date.
Currently, I have three custom functions:
However, when I try to schedule the alert, these custom functions cannot be selected (they appear in red).
Any guidance or help would be greatly appreciated! Thank you!
