194: Metadata name already declared

A line in your document starts with a squirrel @, which marks a metadata declaration. A metadata declaration assigns a value to a metadata name. Except for a handful of recognized names each metadata name may only be declared once per file or quotation block, but one is declared at least twice in your case.

Solution

If you meant to declare one of the metadata names htmlhead, javascript, script, style or stylesheet multiple times – which is allowed – you need to fix typos in them.

Otherwise make sure to declare each metadata name only once. You can list multiple comma-separated textual values for some metadata names in a single declaration, for example:

@ author: S. Powell, L. Cashew
@ class: poem, dark
@ keywords: metadata, declaration, name, error 194, solution
@ robots: index, follow

Note that language is an alias for lang and classes is an alias for class, so do not declare both language and lang or both classes and class in the same file.
