VWAP Support/Resistance Problems

[stephen bell <sbell@xxxxxxxxxxxxx>]

{In the May 2001 Tech. analysis of Stocks & Commodities, George Reyna
presents the following Metastock indicator:

Volume Weighted Ave. Price Support/Resistance

Problem:
The indicator will not plot on any Metastock window.  I checked into the
Metastock website to see if they had a correction to the code, but did
not see any.  Does anyone on this listserv have success with using this
indicator?

Thanks,
