The name box may contain the cell name or the cell reference of the active cell. If more than one cell is selected, only the first or active cell name is shown. Click **fx** option or type equals to begin the formula. This launches the **Formula Editor**. You may either use the **Formula Editor** or type directly into the formula box.
The name box also displays custom names.
For more information on using the **Formula Editor** and entering a formula, refer to [Entering a Formula in Spread Designer](/spreadnet/docs/latest/online-win/overview/spwin-designerguide/spwin-spd-design/spwin-spd-setformula).
