This handles language selection to show formula messages on each language.
We are using an array to store the text messages in different languages, you can store this part in an include (see Using “includes” into your formula)
To test demo
We have done a dummy conditional just to see several messages, just enter “1”, “5” or “10” in the text box to see how messages are shown, then you can change the desired language of the store and repeat the test. (Language selector in the top of page)
