The formula is correct.
Check your Backtester periodicity setting.

Thanks Bill for the response and for the code improvement.  Adding
the AddColumn gets rid of the error message however, when I run the
scan it lists stock tickers who's short term ema is above the longer
term ema as well as stock tickers who's long term ema is above the
short term ema.  There still needs to be some code improvement so
that only the stock tickers are listed who's short term ema is
currently above the long term ema and has been for at least the last
30 day's.  Any ideas?

Alan
