I am not familiar with maps so any help is greatly appreciated!  Can anyone help me understand why I am getting the below error on the below code??  Please note that line 15 is "Map idsCoverage = new Map();"

Thanks in advance for any help!!!

Error: Compile Error: unexpected token: 'Map' at line 15 column 0
