Format

Parameters 

expression - any calculation expression

Data type returned 

number

Originated in version 

7.0

Description 

There are two types of errors: syntax and runtime. A syntax error indicates an invalid calculation. A runtime error, such as Field missing or Record missing, occurs when the calculation currently being run is valid but cannot properly execute. See FileMaker error codes for a list of error codes and messages.

Notes 

  • The EvaluationError function must enclose the Evaluate function to return any syntax errors.

Example 1 

EvaluationError( GetField ( "total" ) + 1 ) returns 102 (Field Missing) when the field total has been deleted or renamed.

Example 2 

EvaluationError( Evaluate ( calculationField ) ) returns 1207 (Unbalanced Parenthesis) when calculationField contains abs(-1 with no closing parenthesis.
