You have three problems, set_fact and when is all lower case.
When you have curly brackets after colon you need quotes around it.
Your When becomes a variable since it is indented to far in, when must be on
the task, indented the same as set_fact.
- set_fact:
Thisvar: '{{ myvar.value }}'
when: myvar.value is defined
