Penstock

Guide / Every rule

A field writes no variable

The check form/no-key, in the group Forms.

Error

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.
