Question:
For user input, I create a name variable because first name was not an option to select. The user input is the save in name variable, but then if I try to fetch the data in the flow its not working.
Answer:
You can add {{first_name}} variable here:
Please make sure to select custom variable instead of global variable. Also, use user-specific custom variable so that values can be changed to whatever is needed.
Additionally, {{first_name}} and {{last_name}} are system default variables and they cannot be overridden, which is it can't be selected on UserInput.
