# Expression Parameter

### General

Some Expressions have additional parameters that may be used within the expression. This type of placeholder can be used to access one of these parameters.

> **Example:** Expressions of style properties of a Table Style have a CellValue parameter that contains the value of the cell for which the style property is being evaluated.

### Syntax

The syntax for this type of placeholder is:

[<name_of_parameter>]

### Example

Let's suppose you write an Expression for the Font property of a Table Cell Style; in that context, the CellValue expression parameter is available, which contains the value of the cell for which the style property is being evaluated. An expression could look like this:

          Expression Parameter Placeholder Example

          

If([CellValue] = "David", "Arial", "Tahoma")

If the value of the cell for which the style property is being evaluated equals David, the cell will have the font Arial; otherwise the font Tahoma will be used.
