The Formula Bar
The Formula Bar displays the selected cell's formula, including any @RISK functions that have been, or will be, inserted into the cell. Changes to the configuration of a distribution will be reflected in the Formula Bar as those changes are made. In addition to displaying the cell's contents, the Formula Bar has two buttons to the far right.
When working with complex formulas that involve more than one @RISK function inside a single cell, the Define Distribution window will only display the configuration for the selected distribution; the selected distribution will be highlighted in the Formula Bar.
To view or edit the configuration for a different distribution function, click the function name in the Formula bar.
Editing Formulas
Primarily, editing of the function is done through the Configuration Panel; however, it is also possible to edit the formula manually. Manual editing of a formula can be done in two ways. The first is to start typing; new input will be inserted where the cursor is located. The second method is to click inside the Formula Bar and use the left or right arrows on the keyboard to set the cursor position and begin editing.
If a distribution function is highlighted in the Formula Bar, it will be overwritten when typing!
After editing a formula, hit Enter or use the Validate Formula button ( ) to check the syntax. If the formula is valid, @RISK will return to the Define Distribution window. If the formula is not valid, a warning prompt will open; clicking Yes will return to editing mode, and clicking No will discard all changes.
