(Harlowe) Trying to add name and gender options

I'm trying to make the main character's name/title/style of address, etc. change based on choices at the beginning of the passage, but I'm running into the "X is not defined" error.

Examples:
[]
[[Aldrovanda(set: $name to Aldrovanda)->Pleased to meet you.]]
<<textinput $name "[[This is my name|Pleased to meet you.]]">>

Fairly certain I'm doing some kind of amateurish mistake, but I'd like it clarified.
