A problem with Totals.gsk and Custom Data fields by W8TTS - 2013-11-27

I'm trying to run Totals.gsk on a filtered set of waypoints. The filter includes selection on two of my Custom Data fields, Bike_Trail & GameLands. And, when I run Totals.gsk, I get the following error:

MacVersion = 1.8
MacDescription = Total any column
MacAuthor = clyde
MacUrl = http://gsak.net/board/index.php?showtopic=...indpost&p=32557

Current Macro: E:\UserData\n\Application Data\gsak8\macros\Totals.gsk

Error in Macro at line: 93
$data = sqlite("sql","select $dbfield, count($totl) as tot from caches where $_where group by $dbField2 order by $sort $sequence","")

Error=> SQLite Error 1 - no such column: Bike_Trail
