There are two kinds of errors, syntax and calculation. A syntax error occurs when an equation is formed in a way PowerOne doesn't understand. When a syntax error occurs, an error alert is displayed in the lower, left corner and each equation with an error shows an error button. Syntax errors are discussed in [https://.../t/help_equations|Equations].

Calculation errors occur when the result of a computation fails. When a calculation error occurs, the error is displayed next to the variable that was impacted. Calculation errors are discussed in [https://.../t/help_variables|Variables].

__This function is only available in templates.__

++error("description")++

Displays the error text 'description'. 'description' must be surrounded by quotation marks (") or will return 'Missing "' calculation error. Generally error() function is used in if statements.

**Internal Error Codes**

You can also access the internal error codes used by PowerOne. For each error, replace "description" with the following:

- "NaN" : not a number

- "posInfinity" : positive infinity

- "negInfinity" : negative infinity

- "divZero" : division by zero

- "noAnswer" : no answer
