Filter Expression Dialog Box

Description

The Filter Expression dialog allows you to specify an association between the current table and the lookup table. A typical circumstance when this would be desirable is when you selected a value in a vendor field and wanted the list that appeared in the product field to contain only the vendor's products.

In the Field Expression (in target table) field enter a field name or expression that can be compared to the Field Expression (in current table) field.
Select a relationship from the Operator field.
In the Field Expression (in current table) field enter a fully qualified field name or expression that can be compared to the Field Expression (in target table) field. When the two expressions and the operator combine to evaluate to TRUE (.T.) then the record will be included in the list; otherwise, it will be excluded.
Optionally, enter a fully qualified field name or expression in the Watch Expression field. When this value changes, the list box will be repopulated.
Optionally, enter a value in the Value to Display If No Matches field.
Click OK to continue or Cancel to discard your inputs.
