# Inserting Formulas

When creating formulas, you have the option of using either Crystal or Basic syntax. Almost any formula written with one syntax can be written with the other. Reports can contain formulas that use Basic syntax as well as formulas that use Crystal syntax.

**Formula Fields**and click**New**.**Tip**To display the Field Explorer, click the View menu, point to Other Windows, and click Document Outline. - In the Formula Name dialog box, enter a name for your formula.

**Check**button to identify any errors in the formula. - Fix any syntax errors identified by the
**Formula Checker**. - When the formula has the correct syntax, click the
