What is wrong with this simple line: and [weekly close < ( Lower weekly EMA Env(11,7) + Lower ...

I add this line to a scan:
and [weekly close < ( Lower weekly EMA Env(11,7) + Lower weekly EMA Env(22,7) )/2 ]

and get this very un-useful error message:
Could not parse "" located in the clause "( LOWER WEEKLY EMA ENV(11,7) + LOWER WEEKLY EMA ENV(22,7) )/2"

or do they mean, we refuse to parse
