[FX.php List] record won't delete

[Edward L. Ford]

Hello,
I'm attempting to get a record to delete, but it refuses to do so with 
the following code:
   
    # Needs the record ID to edit or delete a record
    $EditRecord->AddDBParam('-recid', stripslashes($_POST['RecID']));
   
    # Declare all inputs from HTML form
    if(! (strstr($_POST['delete'], 'Yes') === FALSE)) {
        $EditRecord -> FMDelete();
        # Set a delete flag (Used to display delete confirmation later on)
        $Delete = 1;
    }
I know the block with the delete command is entered because I get the 
delete confirmation message -- but the record is still in the database.  
I also tried $EditRecord -> FMDelete(true); which did not work.

Anyone see my mistake?
Thanks,
