# Property Query Table Dialog Box [GstarCAD 2022](Help%20System/GSTARCAD/2022/Index.md) → [Commands](Help%20System/GSTARCAD/2022/Commands/(Commands).md) → [03 Dialog Boxes](Help%20System/GSTARCAD/2022/Commands/03%20Dialog%20Boxes/(Dialog%20Boxes).md) ## Function Description: This command is used to create and modify a lookup table for custom properties within the dynamic block definition.  **Dialog Box Options:** ## Action Name Displays the associated lookup action name, which you can edit in the Properties palette. ## Add Properties Displays the Add Parameter Feature dialog box.  ## Audit Checks the data to ensure that each row is unique. ## Input Properties Displays the parameters you select in the Add Parameter Feature dialog box as columns. When a parameter value matches the input property column, the corresponding lookup property is assigned to the block reference. ## Select Properties Displays the custom value assigned to the input properties. Click the bottom of a lookup column to make the lookup property read-only or to allow reverse lookup. Allow Reverse Lookup enables a drop-down list associated with the lookup grip that changes the block reference to match the input property values in the table.
