# Checks

> Every problem Fink reports, what it means and how to fix it: missing translations, missing or unknown variables, missing plural forms, unused messages.

Fink checks every message with the inlang SDK's checks, comparing each translation with the language you translate from. Problems appear as a label on the card and under the **To do** filter. They are warnings: you can push with open problems.

| Card label | Check | What it means | How to fix it |
|---|---|---|---|
| **Missing** / **Missing in German, French** | `missing-translation`, `empty-translation` | The language has no translation, or only empty text. Your app shows its fallback. | Choose **Translate to …** or **Start from …** and write the translation, or type into the empty text. |
| **Missing {count} in German** | `missing-variable` | The reference uses the variable `{count}`, the German text doesn't. Users would not see the number. | Choose **Insert {count}**, or type `{` where it belongs and pick `{count}`. |
| **Unexpected {cnt} in German** | `unknown-variable` | The German text uses a variable the reference doesn't have, often a typo. At runtime it would stay empty or appear literally. | Choose **Replace** to use the suggested variable, or **Remove**. |
| **Link missing in German** (or Bold, Italic…) | `missing-markup` | The reference wraps text in markup, such as a link, that the translation lacks. | Use the one-click action, such as **Link {email}** when the markup wraps a variable, or **Add link at the cursor**. |
| **Not split by {count}** | `missing-selector` | The reference has plural or select forms, this language has one text. | Choose **Split by {count}**. See [Plurals](/docs/plurals-and-selects). |
| **No form for 0** | `missing-selector` | The reference has a form for an exact number that this language doesn't choose by at all. | If the message is one text, choose **Split by {count}** first. Then add the form for 0 in **Edit structure…**. |
| **2 forms missing** | `missing-variant` | Some plural, select or exact-number forms that the language needs have no text. | Choose **+ Add … form** or **+ Add a form for 0** for each. |
| **Form one is empty** / **3 forms are empty** | `empty-variant` | One form has no text while others do. The app would show an empty string for it. | Write the form's text, or **Remove** it if it's optional. |
| **Not used in code** | `unused-message` | No call to this message was found in your code. Paraglide JS and next-intl projects, when Fink could resolve every call. | Delete it if it's really unused. See [Unused messages](/docs/unused-messages). |

Fink also shows **Still in English** (or your source language) when a translation started from the source text still contains source words.

## The To do filter

**To do** groups the problems into **Missing translation**, **Missing forms**, **Empty forms** and **Placeholder problems** (variables and markup). The counts cover the languages selected in **Translate into**. The language menu shows how much is open per language.

Unused messages are not counted as to do.
