## Formula Rules
HARDFORMULA and SOFTFORMULA let you configure a column so that its value is automatically calculated from other columns in the same row - just like a spreadsheet formula. When a user opens the editor, the formula is evaluated live and the result is shown in each cell.
### Writing a formula
Formulas use column names, not cell references, so there is no need to know the grid layout. For example, if you have PRICE and VOLUME columns, a REVENUE column formula would be:
```
= PRICE * VOLUME
```
Each row calculates its own result - the PRICE in row 1 is multiplied by the VOLUME in row 1, the PRICE in row 2 by the VOLUME in row 2, and so on.
!!! note
Each column name in the formula must be surrounded by spaces (eg ` PRICE ` not `PRICE`) so it is recognised as a column reference rather than part of a function name. Text inside quotes is left as-is.
### HARDFORMULA vs SOFTFORMULA
* **HARDFORMULA** - the column is read-only. The formula result is always shown and submitted. The user cannot change it.
* **SOFTFORMULA** - the cell shows the formula result but the user can type a different value if needed. If they do, their value is submitted instead.
### Editor behaviour
* When you paste a formula into the grid, column names are automatically translated so the formula works in its new position.
* A cell that has been overwritten by a formula is flagged so you can revert it.
* Formula-looking values pasted from Excel are treated as plain data (not evaluated), unless you explicitly choose "Apply as formula".
### Special values
Formulas can reference three special values that are resolved at runtime:
* `DC.ROW_STATUS` - the current state of the row: `M` (Modified), `A` (Added), `D` (Deleted), or `U` (Unchanged).
* `DC.USER_NAME` - the logged-in user id.
* `DC.ORIG_VALUE` - the original cell value before the current edit.
Example - show the current user id if the row has been changed, otherwise keep the original value:
```
= if( DC.ROW_STATUS != 'U', DC.USER_NAME, DC.ORIG_VALUE )
```
## Regex Rules
HARDREGEX and SOFTREGEX validate cell values against a SAS (Perl-style) regular expression provided in `RULE_VALUE` - the same syntax accepted by [PRXPARSE](https://documentation.sas.com/doc/en/pgmsascdc/9.4_3.5/lefunctionsref/p0s9ilagexmjl8n1u7e1t1jfnzlk.htm).
