[amibroker] actionExploration is not recognized

[tipequity]

The following code produces error 29 Variable 'actionexploration' used 
without having been initialized. Replacing "actionExploration" with "4" 
is the work around.

Buy = (CCI(14) <-100) ;
Sell = (CCI(14) >100) ;

if (Status("ActionEx")  == actionExploration) 
{
Filter = Buy OR Sell;
}
