Assigning a value - Botpress

A newly-created variable is like an empty box—you need put something inside it before you can use it. This is called assigning a value to your variable.

Modifying your prompt

Next, modify the prompt so your bot knows how to work with the variable. Erase everything in the Instructions field, then paste the following:
