iClose - Undeclared Identifier

[nelhajj]

I've been getting the Undeclared Identifier error on iClose, iOpen, iHigh and iLow, and I have no idea how to fix this.

for example in this: 

int      HighestCloseBarBefore = iHighest(NULL,PERIOD_H4,MODE_CLOSE,RoomCandles,(a+1));
int      HighestCloseBarAfter = iHighest(NULL,PERIOD_H4,MODE_CLOSE,RoomCandles,(a-RoomCandles));
double   HighestCloseValueBefore = iClose[NULL,PERIOD_H4,HighestCloseBarBefore];
double   HighestCloseValueAfter = iClose[NULL,PERIOD_H4,HighestCloseBarAfter];

 Can anyone help?

Don't use iClose[], it is iClose()
