The Formula Builder is available from several places in Spotlight Sustain:

- From within the Formula Gallery
- When working on a standard or custom chart
- When creating a KPI

- You can now choose whether you want to select a single account or multiple accounts (you can add more accounts later).

**Standard dates**- Displays data based on the X axis date range. For most charts, this will show monthly values for the current financial year.

If required, to rearrange a symbol or account you can click and drag it within a formula, or drag it to the removal box to remove it completely. The formula works on a BEDMAS basis - please use the brackets to ensure your formulas are correct.

Once you've built your additional formula, click Show series and select the Show check box.

When you create a formula from within a chart or the Formula Gallery, if you want to use it again in future you can save it to the Formula Gallery. You can choose to make your new formula available to all organisations or only a single one, and to use your own formula instead of a default one.

- Use the formula builder to create the required formula, then click Save As.
- From the Available to drop-down list, choose Organisation. If you choose Practice, the formula is available to the whole practice.
- Enter a name for your formula.

*Note:**If you enter a name already in use for a default formula, your own formula takes precedence in this organisation. If you enter a name already in use for another custom formula, the existing one is replaced.*

- If required, enter formula tags.
- To save the formula, click Save.

Your formula is now available to use in charts, text panels, and the Executive Summary page.
