Guide / Every rule
A field writes no variable
The check form/no-key, in the group Forms.
Why it matters
A field with no key is shown to the user, but what they enter is not passed to the process.
How to fix it
Give the field a key, the name of the process variable it should fill.
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 NO-KEY for every form. The form check is lint, so it is free.
