SYMPTOMS

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.

MORE INFORMATION

Steps to Reproduce Behavior

Create a table with two text fields named Field1 and Field2.
Create a report based on this table.
Add the Field1 and Field2 fields to the detail section of the report.
Modify the ControlSource property for the Field1 field as follows:
=Trim([Field1])
Preview the report. Note that the Field1 field contains #Error and that the Field2 field is blank.
Create a form based on the table.
Add the Field1 and Field2 fields to the form.
Repeat step 4.
View the form in Form view. Note that the Field1 field contains #Error and that the Field2 field is blank.
