In Scanner when you are doing copy - paste of script, it gets clubbed all the words in the script, make sure there is proper spaces in between scripts.

Reformatted with spacing:

BUY SIGNAL:

EMA(CLOSE,9) < EMA(CLOSE,21) AND  
REF(CLOSE,1) > REF(OPEN,1) AND  
REF(CLOSE,2) < REF(OPEN,2) AND  
REF(OPEN,1) < REF(CLOSE,2) AND  
REF(CLOSE,1) > REF(OPEN,2)

SELL SIGNAL:

CROSSOVER(EMA(CLOSE,21) , EMA(CLOSE,9))
