 2. **The line is shown in the wrong language.** The `key=` is missing from the mod's `locale` files for that language; the quoted text is shown instead.
 3. **An answer leads nowhere.** The label after `->` must exist in the same file, written with a colon (`:bar`).
 4. **An `action` does nothing.** The mod that owns the action is not part of the game (the log says the action "is not registered"), or a parameter name is wrong — compare it with the action in the scenario editor of Editor Tools.

+## Shared expressions
+
+Numeric expressions are supplied by `expressions_base`. Use `set money=rnd(3,5)` or `cset total "1+2+${money}"`; reuse `${money}` in localized text and action parameters. `set name value` still stores a literal string. See the [Expression Engine guide](../../expressions_base/docs/en.md) for syntax, strict assignments and mod-defined strategies.

 2. **Реплика показывается не на том языке.** Ключа `key=` нет в файлах `locale` мода для этого языка, и вместо перевода показывается текст в кавычках.
 3. **Ответ ведёт в никуда.** Метка после `->` должна существовать в том же файле и записываться с двоеточием (`:bar`).
 4. **`action` ничего не делает.** Мод — владелец действия не входит в игру (в логе написано, что действие "is not registered"), или имя параметра неверное — сверьте его с действием в редакторе сценариев Editor Tools.

+## Общие выражения
+
+Вычисления предоставляет `expressions_base`. `set money=rnd(3,5)` выбирает целое число; `cset total "1+2+${money}"` вычисляет выражение. `${money}` используется в локализованном тексте и параметрах действий. `set имя значение` сохраняет строку как раньше. Синтаксис и расширение стратегиями описаны в [руководстве движка выражений](../../expressions_base/docs/ru.md).
