ACC2000: "#Error" Message Using TRIM() Function in Form/Report

• Microsoft Access 2000

SYMPTOMS

Moderate: Requires basic macro, coding, and interoperability skills.

If a report or a form has its RecordSource property defined as a table that contains no records, "#Error" is displayed when you preview the report or view the form in Form view if a bound control on the report or form is defined by using the Trim() function.

CAUSE

When you use an expression to define the ControlSource property for a form or report, Microsoft Access evaluates the expression and presents the result for the control. If Access evaluates a blank field, it displays "#Error."

RESOLUTION

To avoid this error, surround the RecordSource property with an IIF (Immediate If) statement.
