I can’t tell what failed from just `#ERROR!`. If you paste **the full error message**, plus: 1) what you were trying to do, 2) the tool/app/language (Excel/Google Sheets/Python/etc.), 3) the exact formula/code involved, I can pinpoint the cause and the fix. If this is **Excel or Google Sheets**, `#ERROR!` often means a **formula parse error**. Common fixes: - Use the right argument separator: `,` vs `;` (depends on locale) - Match parentheses: `(...)` - Put text in quotes: `"text"` - Use correct function names for your locale - Check ranges: `A1:A10` (not `A1-A10`) - Make sure you didn’t paste smart quotes or hidden characters Send a screenshot or the formula and I’ll debug it.
