Guide / Every rule
Two fields write the same variable
The check form/key-clash, in the group Forms.
Why it matters
Tasklist and the form editor refuse to open a form in which two fields, or a field and a group, use the same key.
How to fix it
Give each field its own key.
Where you see it
Press Check in the form editor. The Problems tab of the sidebar lists it. In a terminal, penstock check reports it as KEY-CLASH for every form. The form check is lint, so it is free.
