Multiple Select Does Not Delete All Selected Grid Lines in Headerless Detail Form

Hi All,

Should the Multiple Select work for deleting grid lines  in a Headerless Detail Form?  I've done the following but when I select multiple lines and Delete, only one grid line is deleted.

In the Advanced Tab of the Grid Properties, I've selected the option for Multiple Select.  For the menu option Delete, I've coded the event rules to delete.  Under the Options pull down menu within the Button Clicked event rules, I've selected the option for Repeat for Grid.

Thanks,

Sally
