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

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.

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."

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

Steps to Reproduce Behavior

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